Choose the correct name for the incorrectly named molecule 1-isopropylpropane.

Question

Group of answer choices

2-methylpentane

2-isopropylpropane

2-ethylbutane

Answer 1

The correct name for the molecule incorrectly named 1-isopropylpropane is 2-methylpentane.

Here's the reasoning:

1. The name "1-isopropylpropane" suggests that there is an isopropyl group (which is a branched group) attached to the propane backbone.
2. To properly name this structure, you would recognize that the backbone is propane (three carbon atoms), and the isopropyl group is attached at the second carbon when fully drawn out.
3. The correct structure would indeed be 2-methylpentane, which indicates a five-carbon chain (pentane) with a methyl group on the second carbon.

So the answer is 2-methylpentane.
