Solution

Q.
Consider the following sequence of reactions and identify the final product (Z)

$C_{6} H_{6} + {CH}_{2} = {CHCH}_{2} Cl \overset{{AlCl}_{3}}{\to} (X) \to_{(ii) H_{2} O_{2}, {OH}^{-}}^{(i) {BH}_{3}, THF} (Y) \overset{{BF}_{3}}{\to} \underset{Major}{(Z) (C_{9} H_{10})}$

1 ${PhCH}_{2} CH = {CH}_{2}$

2 $PhCH = CH - {CH}_{3}$

3

4 $PhC ({CH}_{3}) = {CH}_{2}$

Solution

Q. Consider the following sequence of reactions and identify the final product (Z) C6H6+CH2=CHCH2Cl →AlCl3(X)→(ii) H2O2, OH-(i) BH3, THF(Y)→BF3(Z)(C9H10)Major

1 PhCH2CH=CH2

2 PhCH=CH-CH3

3

4 PhC(CH3)=CH2
