I am so so happy you exist man❤ I'm sorry you don't have a million subscribers because this is content that is actually making me understand Chemistry and im so grateful for that because falling behind can be really painful
But you're that person that is able to pull people out of that place of not understanding and someone people can depend on to understand a topic
Thank you ❤

[ravjayakodi]

got my y12 paper 2 mock this friday, thanks for this

[ByeBye-ru]

This is so good! I was looking for videos to make a poster and I came across this. You explain it so well and presented it so clearly. Thanks!😊

[xtrasss]

Thank you!!! This is so in depth and explained so well

[gracechen]

A big thank you to you, sir! This video is so so helpful! I was so confused with all the reactions in each group. Now I know how the homologous groups are related to each other through these reactions. The table comparing substitution and elimination of halogenoalkane is extremely helpful! Just one thing to be added on to this video: the mechanism of nucleophilic substitution of halogenoalkane with NaOH/KOH to produce alcohol. I know it's very similar to halogenoalkane with KCN and NH3 but it will be great to included in this video.🙂

[simonghostriley]

thank you so much man im currently in y13 and i got absolutely horrible grades in y12, DUU however this year is a come back arch for me im going to get AAA

[yaramahmoud]

thank you so much for taking the time to make this video! It really helped out alot <3
are you planning to solve pastpapers anytime in the near future?

[almondblossom]

Hi sir, at 26:46, why is one of the products for the right hand pathway H+, and not H20 like the left hand pathway? Thank you!

[ImranAwan-ns]

In nucleophilic substitution, in the reaction with cyanide, why does the I become I- (minus) and 2 electrons, and not just I-. As iodine has 7 electrons, but 1 of these electrons is bonded with the carbon in the bond, if it just gains the electron from the chlorine, should it not be I-? As well as this, why in the reaction with ammonia is there a positive?

[simonghostriley]

real quick question could you explain in electrophiles the part where you said about the C+ being on the right hand side i dont get it 11:10

[KyraYang-gt]

11:27 Does it matter if I draw the purple arrows but drawing a secondary carbocation intermediate? It's a bit confusing to differentiate the two kinds of drawing (of the arrows).

[taiju]

30:26 why is there a lone pair on the oxygen? Since it is in group 6 shouldn’t it be stable since it’s already bonded to the carbon and hydrogen?

[AishaM-kkmg]

Can you please do a similar video with Year 2/ Year 13 mechanisms - it would be really appreciated ?

[sarahj]

I love you thank you so very so very so very much

[PatelHarnisha-gj]

Can you make video on nucleophilic addition

[thee_pauline]

Sir at 25:04 isn't that a primary haloalkane (meaning it undergoes substitution only) so why is the end product a alkene? Shouldn't it be an alcohol or is the end product based on what OH is dissolved in? Please help I'm so confused

[aisha.mospah]

Can you please do a video like this for year 13 mechanisms ?

[gymwniamh]

Can you do a video in Born Haber diagrams
I’m getting confused when to x2 or not for some of the values

[MariamNuhu-fcvz]

sir, in 28:30 isnt the product nitriles and amines not jot alcohols?

[machacooling]

Is this for CIEs too? Or edexel? ocr..which board is it?-
