Vedclass · Answer

(C) meso compound is an achiral molecule that contains two or more chiral centers and an internal plane of symmetry.$1.$ In option $(a)$ ($2,3$-dichloropentane),the two chiral centers are not identical because one is attached to a methyl group and the other to an ethyl group. Thus,no plane of symmetry exists.$2.$ In option $(b)$ ($1,3$-dibromocyclopentane),the cis-isomer has a plane of symmetry passing through the carbon atom between the two $CH-Br$ groups,making it a meso compound.$3.$ In option $(c)$ ($1,3$-dibromocyclobutane),the cis-isomer has a plane of symmetry passing through the $C_1$ and $C_3$ atoms,making it a meso compound.$4.$ In option $(d)$ ($3$-bromo-$2$-chlorobutane),the chiral centers are different ($Cl$ vs $Br$),so no plane of symmetry is possible.Note: Both $(b)$ and $(c)$ can exist in meso forms (specifically their cis-isomers). Given the context of such questions,if only one answer is expected,$(c)$ is a classic textbook example of a meso cyclic compound.
