(B) $1$. The molecular formula $C_8H_{16}$ corresponds to the general formula $C_nH_{2n}$, which indicates an alkene.$2$. Ozonolysis of an alkene involves the cleavage of the $C=C$ double bond to form carbonyl compounds.$3$. The problem states that one of the products is acetone, which is $CH_3COCH_3$. This implies the original alkene must contain a $(CH_3)_2C=$ group.$4$. The compound must also be optically active, meaning it must contain a chiral center (a carbon atom bonded to four different groups).$5$. Analyzing the options, the structure in option $B$ is $3,4$-dimethylhex-$2$-ene, but specifically, the structure shown is $2,3$-dimethylhex-$2$-ene. Let's re-examine the structure: the compound $2,3$-dimethylhex-$2$-ene has a chiral center at the $C_3$ position, which is bonded to a methyl group, an ethyl group, a hydrogen atom, and the $C=C$ group. Thus, it is optically active.$6$. Ozonolysis of $2,3$-dimethylhex-$2$-ene yields acetone and $2$-methylbutanal. Therefore, the correct structure is the one shown in option $B$.

An optically active compound having molecular formula $C_8H_{16}$ on ozonolysis gives acetone as one of the products. The structure of the compound is
