Question

Which two compounds are isomers of each other?

(1) CH3CH2COOH and CH3COOCH2CH3
(2) CH3CH2CHO and CH3COCH3
(3) CH3CHBrCH3 and CH2BrCHBrCH3
(4) CH3CHOHCH3 and CH3CHOHCH2OH

Answer 1

The isomers mean that these substances have the same constitution but with different structure. So among the four choices, the  (2) CH3CH2CHO and CH3COCH3 is right.

Answer 2

Answer: Option (2) is the correct answer.

Step-by-step explanation:

When two or more compounds have same chemical formula but different structural arrangements of their atoms then they are known as isomers.

For example,
`CH_(3)CH_(2)CHO` and
`CH_(3)COCH_(3)` both have same chemical formula as
`C_(3)H_(6)O`.

The only difference between them is the arrangement of atoms.

Thus, we can conclude that the compounds CH3CH2CHO and CH3COCH3 are isomers of each other.
