This has been super helpful! My last MCAT I struggled with remembering “formulas” but using units has made this process much easier!
Thx ❤ , but i guess halogens are ewg , aren't they?
I dont understand why we used that method for question 2?
Simply brilliant! Ive seen many Chemistry Olympiad/ IIT JEE coaches in India actually give a more circuitous explanation on this. Thank you for your insights, I hope you keep sharing them with us!
❤❤❤
What does divide on each side mean? Its not very clear..
Amreen's strategies have definitely helped me rethink questions on SAT and re evaluate them. Her tips and tricks work so well!!!
Thank you so much the explanation is very clear, Try to do one with the ciral carbon attached to one benzine ring 🥰
Impressive explanation mam
Thank you! To clarify core electrons mean that the valence shell is full correct? While valence electrons mean they are in a shell that is not yet full?
That was really helpful TYSM!!
Thank you so much 🙏
Thank you for all your help so far! MCAT prep with you has really helped me understand the content better:)
Thank you for making these formulas more understandable!
Thank you so much for this video!! I could never understand how people said to solve for units and this was such a perfect example!
I am glad this helped!
❤ I love your teaching thank you
Hi! I just purchased your book and I'm excited to learn this way to solve problems. I was doing this practice question and I couldn't figure out how to break the units open. Could you please demonstrate how to in this problem? Thank you for your help in advance. What is the energy of the photons) emitted by the LED at the frequency of 610 THz? (Note: h= 6.6 x 10^-34 J*s) and the answer choices are in J.
First, thank you for watching the video! Second, thank you for purchasing the book; it'll be a game changer on MCAT! As far as solving for the question you posted: since Planck's constant already has the J you need in the answer and we just need to cancel the s out, start by converting 610 THz to 610x10^-12 Hz, and then Hz breaks open into 1/s giving 610x10^-12 1/s which should be written as 610x10^-12/s (610x10^-12 in the numerator and s in the denominator). Now, dimensional analysis: 6.6x10^-34 Js • 610x10^-12/s The s will cancel out leaving only J, so then multiply 6.6x10^-34 times 610x10^-12 to get 4026x10^-22 J, and if the answers are in exact scientific notation, then move the decimal to the left 3 places to get 4.026x10^-19 J. I used calculator cuz I'm lazy tonight, but you'll learn some math-without-calculator and rounding tricks in the book.
If you'd like to see an image of the work I described above, simply email the question to inquiry@praxisacademic.com, and I'll send it... unless you know how to post images in replies here... lol... I don't.
@@PraxisAcademic Thank you so much for taking the time to write this all out! I will be emailing you for the image. I kept getting confused as to why the exponent came out to -22. I thought when you multiply in scientific notation, you add the exponents. So -34 + -12 = -46 not -22 but then I realized Tera is positive 12 not -12. I definitely need math-without-calculator tricks, I had no idea how to multiply 6.6 by 610 any quicker than using lattice lol. Thank you again.
@@cristinamruiz2 You also learn a couple quick and easy tricks to convert metrics in the book! I will look out for your email. Thanks!
@@PraxisAcademic Hi! I tried emailing you but it said your email is "blocking" my message.
this right here is high level explanation, never thought ochem could be that much fun thanks mrs
Thank You! I'm happy you see orgo as fun after this!
THANK YOU SO MUCHHHHHHH
❤❤. Pls continue making it. Pls make a trick for gmp of hydrocarbons.
I will work on a trick for that. Thank You for watching!
Thanks!!
Thank u for saving my time The best video ever ❤❤
I am glad this helped!
I'm currently a uni student and this topic has been taught to me 5 years ago, but this video finally made this concept easy to remember. Thank you.
I am so glad this helped make it more clear! Thank You for watching!
The best video… I really appreciate it🎉
I wish i could like this several times
Awww... that's so sweet of you! I appreciate you liking it!
Very good Explain
Thank You!
thank you SO much... my exam is tomorrow 😅
Thank You for watching and using my trick. I hope the exam went well!
Spectacular explanation mam :) I love it and Thanks for your efforts
Thank You for watching!! I appreciate your feedback!
oh my god thank you! i finally get it. i was so frustrated and disheartened trying to figure this out last night
I'm glad this helped!
The NO2 has 5 connections to the nitrogen where it usually prefers 3 and one lone pair <3. I love the trick though thank you so much!
Thank You for pointing that out. I forgot to dash-out one bond on each of the O atoms to show resonance in the nitro, and there's not way of editing it now. I did include the correction in the description. Thank You for watching! And thanks for the feedback!
Seriously, I can't thank you enough. In less than ten minutes you taught me something that hours of content couldn't.
Thank You again! I truly appreciate your feedback! 🤍
Thank you for teaching this in a way that doesn't require a masters degree in quantum physics, no one knows how to teach people that have practically no prior knowledge.
I am so glad this helped you! Thank You for watching!
This really helped!! Thank you and God bless you
I'm so glad this helped! Thanks for watching and using our tactics!
i love you
lol... thanks! And I hope this helped in orgo!
Here's one more trick.....if the central atom of the attached group has a lone pair it is ortho para directing but if it has a pi bond then it is a meta directing 😅 hope it helps 😊
Thank You so much for sharing this! This will of course be helpful!!
helped me a lot for jee examination
I'm so glad this helped on an exam! Thanks for watching!
incredibly helpful, thank you amreen!
so helpful! thank you amreen. there truly is no better trainer thank you!
love amreen! truly the best. highly recommend her to anyone, especially for mcat prep!
Thank you so much, you just helped me understand this mcat q!
I am glad this helped. I hope it helps on more BP-VP Qs... they can be a bit tricky on MCAT. I appreciate your feedback; all my videos, except Significant Figures... lol... are MCAT and DAT geared! Thanks for watching!
amazing explanation!
Thank You and thank you for watching!
Well cyclooctatetraen isn’t planar in the first place
True... cyclooctatetraene predominantly exists as tub-shape due to its irregular bond lengths, however, I intended to show its planar transition state between its tub-shapes which is antiaromatic. I showed its antiaromatic state because that's how they usually show it on DAT or MCAT. If they were to show the 3D tub-shape, then indeed it would be nonaromatic. Thank You for watching!
good stuff
Wonderful lecture as suits your channel name
Thank You! I appreciate your feedback, and thank you for watching!
Thank you madam❤
If vapou pressure becomes equal to atm pressure dont they cancel out each other?if it happens then how ?please reply😢
Atmospheric (gas) pressure is constant (ie: 1atm at sea level). The vapor pressure of liquids and solids are lower than atmospheric pressure (solids are lowest). When the surface molecules of a liquid or solid reach 1atm, usually due to temperature increase, the surface molecules of the liquid or solid will become gaseous. Liquids or solids reaching 1atm does not cancel out atmospheric pressure since that is constant (cannot be changed); liquid or solid molecules that reach 1atm vaporize into gas molecules--think of this as, if gases have a vapor pressure of 1atm, then any liquid or solid that obtains a vapor pressure of 1atm will become one with the atmosphere gas.
@@PraxisAcademic now i feel better thank you btw example was great ❤️
I was unable to understand these things before watching this video... And you made it such a way... Wow i don't have words to express how i feel now!!! Thank you so much!!!❤
I am glad this helped! Thanks for watching!
excellent! Thank you!
Thanks for watching!
My professor never taught me this. I have my final exam tomorrow and I have tons of things to study, this made me way easier to learn this topic since I don't have so much time to memorise and remember so many things. Thank you so much!
I am so glad this made it easier for EAS. I hope your final went well!
Just the kind of explanation I needed to clear my concept. It's just wonderful how you made it so easy to understand. Thank you so much😊
Thank You! I am so glad this made it more clear and easier to understand EAS! Thanks for watching!
