Vedclass · Answer

(A) The structure of $2$-methylbutane is $CH_3-CH(CH_3)-CH_2-CH_3$.Monochlorination can occur at four different types of hydrogen atoms:$1$. At $C_1$ (terminal methyl group): $CH_2Cl-CH(CH_3)-CH_2-CH_3$. This molecule has a chiral center at $C_2$, so it exists as $2$ enantiomers.$2$. At $C_2$ (tertiary carbon): $CH_3-CCl(CH_3)-CH_2-CH_3$. This molecule is achiral ($1$ isomer).$3$. At $C_3$ (secondary carbon): $CH_3-CH(CH_3)-CHCl-CH_3$. This molecule has a chiral center at $C_3$, so it exists as $2$ enantiomers.$4$. At $C_4$ (terminal methyl group): $CH_3-CH(CH_3)-CH_2-CH_2Cl$. This molecule is achiral ($1$ isomer).Total number of isomers = $2$ (from $C_1$) + $1$ (from $C_2$) + $2$ (from $C_3$) + $1$ (from $C_4$) = $6$.
