(iii) CH3-O-CH (CH3)2 (iv) CH3CH2NH2 (v) HCHO (vi) (CH3)2NH​

Answer 1

Answer:

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
