Vedclass · Answer

(B) Structure $A$ is $1$-chlorobut-$2$-ene $(CH_3-CH=CH-CH_2Cl)$.Structure $B$ is $2$-chloro$-2-$methylprop$-1-$ene $(CH_2=C(Cl)-CH_3)$.These are structural isomers,specifically functional/positional isomers,not diastereoisomers. Diastereoisomers are stereoisomers that are not mirror images of each other.Since they have different carbon skeletons and functional group positions,they are not chain isomers either.However,evaluating the reactivity: $A$ is a primary allylic halide,which is highly reactive in $S_N2$ reactions due to less steric hindrance. $B$ is a vinylic halide,which is generally inert to $S_N2$ and $S_N1$ reactions.Therefore,the statement that $A$ and $B$ are chain isomers is incorrect as they are structural isomers with different connectivity.

Identify the incorrect statement regarding the given structures $A$ and $B$.
