Q.
(A) Aryl or alkyl monochloride $\xrightarrow[(ii)H_3O^{\oplus}]{(i)Mg, Re \ext{flux}}(B)$
How many isomers of $(A)$ will give $(B)$. When $(B)$ is -
(a) $CH _{3}- \underset{\overset{|}{CH_3}}{C}H - CH _{3}$
(b) $CH_3-\underset{\overset{|}{PH}}{C}H-Ph$
(c) $CH _{3}- \underset{\overset{|}{CH_3}}{C}H - CH _{2} CH _{3}$
(d) $Ph CH_2-CH_3$
For example if $abcd$ each are formed from $3$ isomers of $A$ in every case fill $3333 .$
Haloalkanes and Haloarenes
