Question

Of the organic compounds below which ones have isomers of nonane are

1) 1,2,4-trimethylcyclohexane
2) 2,2,4,4-tetramethylpentane
3) 3-ethyl-2,2-dimethylpentane

Answer 1

[AI-generated answer — Bot GPT 3.5]

1) 1,2,4-trimethylcyclohexane does not have isomers of nonane. It is a cycloalkane, not a straight chain alkane like nonane.

2) 2,2,4,4-tetramethylpentane does not have isomers of nonane. It is a branched alkane.
3) 3-ethyl-2,2-dimethylpentane does have isomers of nonane. The isomers would be different arrangements of the carbon atoms in a straight chain with nine carbons.
