Give names of following compounds.
(a) CH3-CH2-CH=CH-CH2
(b) CH3-CH2-CH(CH3)-CH(CH3)-CH3
(c) CH3-CH=CH-CH2-CH=CH2​

Answer 1

Answer:

The IUPAC names of the compound are as follows:

a.) 2-methylpentane

Using the lowest locant rule, the branched methyl group is present at the carbon numbered 2

b.) 3-methylhexane

The maximum number of carbon chain in this case is equal to 6 which is possible if the methyl group is considered to be branched
