First off, i really like your videos and they are a great source of revision for my A levels. I have only one minor gripe with this video and that is your structural diagram of sulphuric acid. I know that it is meant to be in a 3 dimensional space, but if you want to draw it in 2 dimensions it is much more accurate to draw the double bonded oxygen atoms on the left and right hand side of the Sulpher atom and the hydroxyl groups above and below instead of both hydroxyl groups above and both double bonded oxygen atoms below as you have drawn.

[@xxpinkladiesxx]

Hey :), in my chemistry notes it explains something called ‘Markownikoff’s Rule’ that says 'In most cases, bromine will be added to the carbon with the fewest hydrogens attached to it' but should I stick to your method of the alkyl groups attached instead?

[@MrERintoul]

xxpinkladiesxx Markonikov's rule is just a fancy way of describing what I said. You are looking to produce the most stable carbocation intermediate and so the initial addition will happen to create this stable carbocation - and this will be the carbocation that has the most alkyl groups attached!

[@ngkean9743]

the br- is not nucleophile?

[@hafsahr741]

Thank you so much YOUR VIDEOS ARE SO EASY TO UNDERSTAND! Thank you again :)

[@shellypathaniachandel9460]

Sir, shouldn't the lone pairs at 12:11 on Br(negative) be different(in symbols), as one of the electrons has been taken away hydrogen(heterophilic) and one was originally from bromine.

Mechanism? I'm not sure if you're getting confused but there is no mechanism for polymerisation? All you need to know at AS is that monomers join together via addition polymerisation to form polymers.

Do you not draw the product in the AS test?

[@abdulrahmanur-rehman4715]

Excellant explanation! I can now finally comprehend Organic reactions although im abit concerned about how you gave the Br2 bond a partial negative and a partial positive charge because what i was taught is that a homolytic fission occurs between elements that are the same so one electron goes to each Br ion. If you could kindly quickly reply since ive got an As exam in 2 days and clear my doubts that would be amazing anways God bless 🙏🙏🙏

[@daniturner1750]

Is electrophilic addition and hydrogenation the same thing. So would electrophilic addition be the reduction of an Alkene?

[@rrj1010]

Oh I know it's in the specification but I've been given questions that "stretch us" and involve a free radical mechanism, eg when making LDPE oxygen impurities are needed as the oxygen free radical initiates the reaction and etc I just thought it would help with the understanding

[@MrERintoul]
