Question

identity the type of isomerism present in CH3COCH3 and CH3CH2CHO

Answer 1

acetone and propanaldehyde (CH3COCH3 and CH3CH2CHO) are a pair of functional isomers

Answer 2

Answer:

Functional group isomerism.

The given compounds acetone (CH₃COCH₃)and propionaldehyde (CH₃CH₂CHO) are examples of functional group isomers.

Explanation:

• The structural isomers with the same molecular formula but differ in their functional groups are functional group isomers.
• In the given example, both the compounds have the molecular formula C₃H₆0.
• They differ in the functional groups, acetone has a ketone functional group.
• The propionaldehyde has aldehyde as its functional group.
• As they differ only in their functional groups, they are called the functional isomers.

Answer 3

The compounds CH₃COCH₃ and CH₃CH₂CHO show functional isomerism.

• The isomers are chemical compounds with the same molecular formula but with different arrangements of the constituent atoms.

• The compound CH₃COCH₃ is propanone. It is a ketone and has a carbonyl group.

• The compound CH₃CH₂CHO is propanal. It is an aldehyde and also has a carbonyl group.
• The propanone has a (-C=O) functional group, and the propanal has a (-CHO) functional group.

• The molecular formula and number of carbon in the parent chain are the same in both the compounds.
• Hence, both compounds have functional isomerism.
