EDEXCEL Topic 6 Organic Chemistry I Part 2 of 2 REVISION

[@Warboss777]

tip: use 1.25 or 1.5x speed if you know most of the content and are just revising quickly

[@sebastianpapageorgiou2825]

damn didn't think of that. great tip thanks

[@a.human.]

YOU'RE A HERO. you saved countless students' grades by posting these really helpful vids, I can never THANK YOU ENOUGH.

[@miaxx3929]

These videos have literally saved my a levels, thank you so so much

[@AlleryChemistry]

You are so welcome!

[@adambukhari8512]

This guy is LEGENDARY

[@skxdi]

Really helpful for the exam today, thanks.

[@AlleryChemistry]

Good luck with your exam. Go and show them examiners what you know!

[@bfgad9701]

Bro you was the reason I passed AS. Imma need you to pull through in A2 dawg. I need those Edexcel chem topics. I appreciate you're a busy man. But i need you to appreciate my struggle and please come through with those good quality vids i need. Or atleast can you direct me to a youtube account which has good content such as yours

[@AG-ql1sy]

very sad how u act like ur the sun and everyone is a planet orbiting around u and owes u something. nevertheless, hopefully u did pull through

[@PhoenixPlayz]

33:48, I believe the ketone is drawn wrong - the middle carbon with the double bond O has 5 bonds

[@PhoenixPlayz]

You realised at 36:59 :D

[@estherfrancis2702]

If only I had this last week for the retake :(

[@sallyj577]

God bless you sir

[@zahraareeves2408]

Thank you very much sir, this is very helpful!

[@AlleryChemistry]

You are welcome!

[@flubbedup411]

Thank you so much for this! :")

[@ftyhbn]

in the combustion reaction shown at 31:52, the state of H2O was gaseous. It should be liquid right?

[@moonisahmed931]

May God bless you!!!!!

[@sara1997]

Why does primary alcohols react the slowest

[@karishmadeegan8297]

Hi Sir, will you be posting revision videos for the rest of the A level course? I've watched all of your whiteboard videos and they were very helpful but having the whole topic in a format like this would definitely be very useful. I greatly appreciate your dedication to teaching, Mr Harris. Many Thanks, Kari

[@jasmineshaw4358]

Thank you, super helpful!

When haloalkanes react with ammonia, why does the nitrogen atom in the intermediate end up with a positive charge ?

[@AlleryChemistry]

Nitrogen has 4 bonds in the intermediate. But is more stable with 3 hence the positive charge.

[@mayanshupadhyaya7741]

@@AlleryChemistry steric hinderence?

[@ramyagururajan]

@@AlleryChemistry hi sir, but how does the number of bonds deduce the fact that it has a positive charge ?

[@nemoland426]

@@ramyagururajan Ammonia form bonds with both hydrogens and carbon, so it has *4 bonds* in total (instead of the usual 3). The ammonia loses one of its electrons to be shared with carbon, hence the +1/positive charge.

[@katiebalme9339]

thanks! are you making any of these revision videos for a2?

[@karsondhakal8139]

Do we have to know the practicals fully for the exams?

[@jet3272]

It’s good to know your practicals since many questions are application questions related to the practicals you did. Though you probably don’t need to know the whole method for each practical.

[@mahmudahoque5543]

Why didn't u make something like this for year 2 😭

[@user-op5jt4eu5i]

Hi sir, at 34:01 you said there shouldn’t be an H on the C=O could you explain what you meant by that. Thank you!

[@aatifmehmood3385]

This is because the Oxygen has a double bond meaning it only requires two more bonds to become stable and therefore he is saying that he accidentally added another bond which is the carbon bond making 5 bonds which is unstable so that’s why you would get rid of the hydrogen on the bottom

[@aatifmehmood3385]

Siuuuuuuu

[@maahirbharadia7487]

Are there revision videos for year 2?

[@maahirbharadia7487]

Nvm I found it! :)

[@tamerrayyan1333]

Is this gcse or a levels. I’m guessinng it’s gcse

[@garimagrg6796]

it's a levels- says in the description ^^
