What is the relation between 3-Ethylpentane and 3-Methylhexane ?A Chain isomers B Position isomers C Functional isomers D No relation

Understanding the Question

To determine the relationship between 3-Ethylpentane and 3-Methylhexane, we need to analyze their structures and how they are categorized in organic chemistry.

Structural Analysis

1. 3-Ethylpentane: This compound has a five-carbon (pentane) chain with an ethyl group (–C2H5) attached to the third carbon. Its molecular formula is C7H16.

2. 3-Methylhexane: This compound has a six-carbon (hexane) chain, with a methyl group (–CH3) attached to the third carbon. Its molecular formula is also C7H16.

Identifying the Relationship

• Both compounds have the same molecular formula (C7H16), which indicates that they are isomers.
• Since they have the same molecular formula but different structural arrangements, they fall under the category of chain isomers (as they differ in the arrangement of the carbon skeleton).

Final Answer

The correct answer is: A. Chain isomers.
