there was this question on structural isomers i put 7! and for the three reasons why is better for process 1 i said higher atom economy, uses catalyst and uses lower atomospheric pressure

how about the mechanism how did you draw them lol , erm and how many marks was that radical question .

there were 10 marks it was easy the same so u had to put the dipoles and show an arrow from bond to Br and an arrow coming down from double bond e.t.c and the last one was nucleophilic substitution and was heterolytic fission

yh i did that i just got feeling i made a dumb mistake, drew the mechanism on the wrong place for electrophllic addition it was confusing where you had to draw it .

yh i drew two of them with a line between them to conncect with each other was shocked when that came up never saw those!! before and for the three reasons for process 1 i said about higher atom economy uses catalyst and uses lower atomospheric pressure

i wrote about higher ataon aconomy and talked about two reasons for catalyst like an idiot i talked about yield aswell :frown:

, probz lost 1 mark on that question

yh i wrote exactly for first point higher atom econcomy, then i worte catalyst saves energy cost then thir point i saw that it uses a lower pressure! cause those were the three differences ?

actually thinking about it the paper was not really easy and people say is easy but then say they have made silly mistakes !

what did u get for the question on equilibrium about catalyst for the first point said stays the same and second point said is to the right hand side?
