Vedclass · Answer

(D) $1$. The structure is $CH_3-CH(OH)-C(=O)-CH_2-CH_3$. The ketone group $(>C=O)$ has higher priority than the hydroxyl group $(-OH)$ according to $IUPAC$ nomenclature rules. Thus,the ketone is the principal functional group and $-OH$ is a substituent. Option $(B)$ is false.$2$. The $-OH$ group is attached to the $C-2$ carbon,which is bonded to four single bonds,making it $sp^3$ hybridized. Option $(A)$ is false.$3$. Counting the atoms: $5$ carbons,$10$ hydrogens,and $2$ oxygens. The molecular formula is $C_5H_{10}O_2$. Option $(C)$ is false.$4$. The longest carbon chain containing the ketone group has $5$ carbons (pentane). Numbering from the left gives the hydroxyl group at position $2$ and the ketone at position $3$. The $IUPAC$ name is $2-$hydroxypentan$-3-$one. Option $(D)$ is true.
