Vedclass · Answer

(D) $1$. To determine the correct $IUPAC$ name, we must identify the longest carbon chain and number it such that substituents get the lowest possible locants.$2$. Option $A$: $4-(1, 1-	ext{dimethylethyl})-2-	ext{methylpentane}$ is incorrect because the longest chain is actually a heptane derivative $(2, 2, 4-	ext{trimethylheptane})$.$3$. Option $B$: $1-	ext{aminobutan}-1-	ext{one}$ is not a valid $IUPAC$ name; the structure is likely $butanamide$.$4$. Option $C$: $2-	ext{ethyl}-3-	ext{methylpentane}$ is incorrect because the longest chain is a hexane chain $(3, 4-	ext{dimethylhexane})$.$5$. Option $D$: $3-	ext{ethyl}-2-	ext{methylpentane}$ is a correct $IUPAC$ name as it follows the rules for selecting the longest chain and assigning the lowest locants to substituents.
