Explanation:

3-Ethylpentane:

Structure: \( CH_3-CH_2-CH(CH_2CH_3)-CH_2-CH_3 \)

It is a 5-carbon chain (pentane) with an ethyl group at position 3.

3-Methylhexane:

Structure: \( CH_3-CH_2-CH(CH_3)-CH_2-CH_2-CH_3 \)

It is a 6-carbon chain (hexane) with a methyl group at position 3.

Relation:

Both compounds have the same molecular formula: \( C_7H_{16} \), but differ in the arrangement of their carbon chains:

3-Ethylpentane: A pentane chain with an ethyl substituent.
3-Methylhexane: A hexane chain with a methyl substituent.

This difference in the carbon chain structure makes them chain isomers.

Answer: The relation between 3-Ethylpentane and 3-Methylhexane is chain isomers.
