- Another family of chemicals with a carbonyl group in. Take a peek at this video to find out how to name carboxylic acids, physical properties and chemical reactions with metals, bases and carbonates. #usefulacids
You are an absolute gem Mr.Chris, thank you for saving me from failure multiple times
Videos are done exactly the way new spec is set out. thank you so much pal
You're welcome! I have separated the videos for the new AQA, OCR A, and Edexcel specs so I hope this is easier.
It is the perfect format. Clear, simple and effective. Thank you sir!!
I have one question about the hydrogen bonding formation between a carboxylic acid molecule and a water molecule.
At about 4:30 of the clip, you drew a line between the hydrogen molecule and one of the lone pair on the oxygen, illustrating a hydrogen bond. So my question is can hydrogen bond be formed between both of the two lone pairs or just once like what you have drawn.
You're honestly the best! I've been binge watching mostly all of your videos! Thank you so much.❤
Yo you're being an absolute legend doing videos like this. Thanks a lot for carrying on despite small following but we are benefitting from you.
Is there a course you're following when you do the videos??
If it's ok to ask can you do some A level AQA videos, the new course for 2015 which doesn't have an AS to it all exams at the end of Y13.
Thanks
+Lachlan Eaton Thanks for your feedback! Yes I would like them to be used by as many people as possible. Sharing the videos help though! The videos cater for all board as most cover similar content with only a small percentage difference. The AS and A2 splitting is still in place due to the Current A2 syllabus remaining valid. This will change from next academic year though to just year 1 and year 2 Chemistry. The new spec has very little changes in terms of content to the old one so the videos are still very relevant to the new AQA spec. On that note there is a new time of flight mass spec video that I made last week, this is specifically for AQA ruclips.net/video/NyIAPU7usfo/видео.html. Big changes in the pipeline so watch this space! Thanks for your support!
+A Level Chemistry Revision Videos by Allery Tutors Ok thanks I was hoping for that kind of response.
Its perfect Nice Job Harris :) , Perhaps you can also include that the high melting and boiling temperature of Carboxylic Acid is Due to its Dimer Formation** :)
Rest is Absolutely Perfect :)
Thank mate ! wish you all the best in 2016!
+Tan Ben No problem! Happy new year to you too! Let's hope 2016 is a blast!
2016 was a blast
is there any need of specifying the '2' in 2-methylpropanoic acid since that's the only possible position of the methyl group in propanoic acid? (i.e. the methyl group can't be attached to the first carbon atom obviously and it can't be attached to the third carbon, otherwise we'd name it butanoic acid, so the only carbon atom it can be attached to is the 2nd one for it to be methyl propanoic acid)
No need, if there's only one position for the methyl group then you can just leave it as methyl propanoic acid but tbh, it doesn't matter too much cause both answers will get you the mark
My love for you knows no bounds
Hi Chris I absolutely love your videos! Very useful and they are helping a lot. In this video you said that a hydrogen bond can only take place with a delta positive hydrogen on one molecule and a delta negative oxygen on another molecule with a lone pair of electrons. Therefore does the oxygen in the carboxylic acid contain a lone pair of electrons, or not? Thank you
You're welcome. Yes, there are lone pairs of electrons on the oxygens in carboxylic Acids so they can hydrogen bond.
Quick question: why is it called Ethanedioic acid, I would have thought it would be called diethanoic acid?
Hello are these the same as Hydroxyacids? Please answer, thanks
