Question

what type of isomerism is exhibited by pentan-3-one and pentan-2-one

Answer 1

Answer:

Position isomerism exists between pentan-2-one and pentan-3-one.

It is due to the difference in the position of the carbonyl group in the same carbon chain.

2-pentanone is CH3COCH2CH2CH3

3-pentanone is CH3CH2COCH2CH3
