Question

Which of the following compounds are constitutional isomers of each other?

a) C6H12 and C4H10
b) C2H6 and C3H8
c) CH3CHO and CH3COCH3
d) C4H10 and C5H12

Answer 1

Option c) CH3CHO and CH3COCH3 are constitutional isomers of each other.

Step-by-step explanation:

Constitutional isomers are compounds with the same molecular formula but different structural formulas. Let's go through each option:

a) C6H12 and C4H10: The number of carbon atoms in these compounds is different, so they cannot be constitutional isomers.

b) C2H6 and C3H8: These compounds have the same number of carbon atoms but different hydrogen atoms. So, they cannot be constitutional isomers.

c) CH3CHO and CH3COCH3: These compounds have the same number of carbon atoms but different arrangement of atoms. Therefore, they are constitutional isomers of each other.

d) C4H10 and C5H12: These compounds have different molecular formulas, so they cannot be constitutional isomers.

Therefore, option c) CH3CHO and CH3COCH3 are constitutional isomers of each other.
