Ans Qus no.68 Q.68. In the following reactions 'X' and 'Y' respectively are (1) (2) (3) (4) Share with your friends Share 0 Vartika Jain answered this Dear Student, The correct answer is (2)The first reaction is Markovnikov's addition reaction. The reaction here proceeds via formation of carbocation.More substituted product is formed so Br shoul attack on CH of -CH=CH2. However benzyl cation is more stable so rearrangement will occur to give X in (2)The second reaction is Anti-Markovnikov's addition. Less substituted product is formed in this case, so Br will attack on CH2 of -CH=CH2. This reaction occurs via free radical mechanism so no rearrangement will occur in this case. 0 View Full Answer
