    to one carbon i had a methyul group and a hydorgen atom and to the opther carbon i had a ethyl group and a hydrogen carbon
    yh thats what i got for the sterosiomer what about the strucural isomer

    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

    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 .

    they did it purposely as cyclic to confuse people !!!! i think they like us to lose marks

    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 , 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 ?

    yh i just rememberd i talked about the crude oil saying its non renewable aswell , catalayst i wrote less co2 being released and toxic gases .

    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?
