1.	(i) CH_3-CH(CH_3)-CH(OH)-CH_(3)overset(H^(+)//Delta)to Aoverset(HBr)toB. IdentifyA and B (major products). (ii)Describe the mechanism of sulphonation of benzene.
Answer» SOLUTION :(i) (ii) Step 1: Generation of `SO_(3)` electrophile : `2H_(2)SO_(4)toH_(3)O^(oplus)+SO_(3)+HSO_(4)^(Theta)` Step 2 : Attack of the electrophile on benzene RING to form areniumion: Step 3: Rearomatisation of Arenium ion:
