Vedclass · Answer

(C) The structure of mesityl oxide is $(CH_3)_2C=CHCOCH_3$. To name this compound according to $IUPAC$ rules: $1$. Identify the longest carbon chain containing the functional group (ketone) and the double bond. The chain has $5$ carbon atoms,so the parent alkane is pentane. $2$. Number the chain starting from the end closer to the ketone group: $C_1$ is the methyl carbon,$C_2$ is the carbonyl carbon,$C_3$ is the $CH$ group,$C_4$ is the $C$ group,and $C_5$ is the methyl group attached to $C_4$. $3$. The ketone is at position $2$,and the double bond starts at position $3$. There is a methyl group at position $4$. $4$. Combining these,the name is $4-$methylpent$-3-$en$-2-$one.
