- Lots of carbs in this video! Well the carbo cation variety. View this video to find out the mechanism between alkenes and hydrogen halides. This tricky one also talks about the importance of carbo cation intermediates and why we produce different isomers of haloalkanes. All explained in a clear and simple way! Phew!!
sir my ALLAH blessed you , sir your lecture is so helpful to learn about the topic
just a tip- if you could add a few exam questions and answers at the end it would really be a great addition to your videos. Exam questions will really help us test what we have learned. However, the downside is that your videos will be longer which can put some quick revision students off. In my opinion, the longer the better. You explain every little thing in a way that actually makes sense. I would let you replace my chemistry teacher any day.
Your videos are the best and most helpful when I can't get around to touch my hard copy material because it seems so scary to dive in!
Thanks a lot! :)
+Fajr Abbas Ha! Thanks, yes they should be used alongside all other forms of revision as you say. It's a bit easier to watch a vid then read from a text.
Yeah! :)
UR VIDEOS ACTUALLY SAVE NY LIFE
THANK YOU SO MUCH!!! :D
legend!

This is so helpful for my unit 2 resit
+Ghost In The Mirror Brilliant. More alkene vids to be added too. Watch this space!
Ghost In The Mirror hope you've done well, what was your grade?
Thank you, God bless you
You are so welcome!
can the 1-bromopropane be separated from the 2-bromopropane to obtain pure 2-bromopropane in industry?
It is usefully thank you sir🌺
Most welcome
how would you draw a tertiary one?
How to know which one to put delta + and delta - on on a hydrogen halide?
when going by primary, why does the hydrogen go to the left carbon not the right? why can't it go to either? (5:49) Also, what causes the carbon to have the positive charge?

Sir,can you please explain me the oxidation of alkenes with hot and concentrated potassium manganate?
+ZBK You must be doing CIE then? Basically KMnO4 is a very powerful oxidising agent and when added to alkenes cold you produce a diol (a molecule with 2 alcohol groups in). When we heat a stronger, more concentrated batch of KMnO4 we get a variety of different products depending on the alkene. If for example we has an alkene and the C in the C=C has 2 Hs on the C=C is broken and CO2 is produced. If the C on the C=C has an alkyl group and a hydrogen then an aldehyde is made this can be oxidised further to a carboxylic acid. If the C on the C=C bond has 2 alkyl groups attached to it will form a ketone. Ketones can't be oxidised any further so this is all you will get. I will add this to my list of videos to do but I can't guarantee it will be done before the exams this summer. So busy arghhh! #examseason
+Allery Chemistry Thank you so much for all you help. I have got it now,thanks once again. And yes I am doing CIE
+ZBK Brilliant! You may be interested that I have daily multi choice questions for AS Chem on twitter follow @allerytutors to get them. Good luck with your course!
+Allery Chemistry I will definitely check your account. Another question,how many years of past papers do you think are enough for an A/A*? I know the more the better but what is a safe number to do. Really worried because I have to meet my condition. Thanks a lot!
+ZBK That's a difficult one. Really you should try to do them all however that may not be possible. It's more about the quality of revision rather than quantity. Use the past papers but learn from the mark scheme. Knowing what the examiners want is your biggest weapon!
