Vedclass · Answer

(C) Let us evaluate the given names:$A$: The structure is $C_6H_5-CH_2-COOH$. The $IUPAC$ name is $2-$phenylacetic acid or $2-$phenylethanoic acid. This is correct.$B$: The structure is $NH_2-CH_2-CH=CH_2$. The numbering starts from the carbon attached to the amine group. The name is $	ext{prop}-2-	ext{en}-1-	ext{amine}$. This is correct.$C$: The structure is a cyclohexane ring with a $-CHO$ group and a $-CH_3$ group at the $3-$position. When the $-CHO$ group is attached to a ring,the suffix used is $	ext{carbaldehyde}$. Thus,the name is $3-$methylcyclohexanecarbaldehyde. The name '$3-$methylcyclohexanal' is incorrect.$D$: The structure is $(CH_3)_2C=CHCOCH_3$. Numbering from the ketone end gives $4-	ext{methylpent}-3-	ext{en}-2-	ext{one}$. This is correct.Therefore,option $C$ has the incorrect $IUPAC$ name.

$A$. $HCHO$	Formaldehyde
$B$. $C_6H_5NH_2$	Aniline
$C$. $CH_3CH(CH_3)CH_3$	$n-$Butane
$D$. $CH_3CH(OH)COOH$	Lactic acid
