Step by step solution
Finding IUPAC name for the compound (a)
The compound model can be represented as,
It is the derivative of benzoic acid with the atom of bromine on C3 and group of methoxyl on C4. The IUPAC name can be named as 3-bromo 4-methoxybenzoic acid.
Finding IUPAC name for the compound (b)
The compound model can be represented as,
It is an unsaturated acid with 4 carbon straight chain in addition to the presence of double bond between C2 and C3. The IUPAC name can be named as 3-methyl 2-butenoic acid.
Finding IUPAC name for the compound (c)
The compound model can be represented as,
It has cyclopentadiene ring which attaches the carboxyl group.
The double bond present between C1 and C2 & C3 and C4. The IUPAC name can be named as cyclopentane 1,3-dienecarboxylic acid.
Finding IUPAC name for the compound (d)
The compound model can be represented as,
It is a carboxylic acid with the 3 carbon straight chain which attaches methyl group to C2 and cyclopentyl group to C3. This has C2 chiral carbon with optically active compound.
The first highest, second and third consecutive groups can be viewed in the anti-clockwise direction.
The IUPAC name can be named as (S)-3-cyclopentyl-2-methylpropanoic acid.
