Organic Chemistry MCQ question and answer with solution | Chemistry Gk MCQs

In organic chemistry, chain isomers refer to compounds that have the same molecular formula but differ in the arrangement of carbon atoms in the carbon chain.

For the molecular formula C₇H₁₆, there are 9 different chain isomers that can be formed. These isomers are based on various structural arrangements of the carbon chain, where the positions of branches or substituents differ, leading to different compounds.

Chain isomers are compounds with the same molecular formula but different arrangements of the carbon skeleton.

The 9 chain isomers of heptane are:

1. n-Heptane
2. 2-Methylhexane
3. 3-Methylhexane
4. 2,2-Dimethylpentane
5. 2,3-Dimethylpentane
6. 2,4-Dimethylpentane
7. 3,3-Dimethylpentane
8. 3-Ethylpentane
9. 2,2,3-Trimethylbutane
