Question

Quizplus · Accepted Answer

The condensed structural formula for 3-ethyl-4-methylheptane is CH3CH(CH3)CH2CH2CH(CH3)CH2CH3. In this formula, the ethyl group (CH3CH2-) is located on the 3rd carbon atom and the methyl group (CH3-) is located on the 4th carbon atom. Choice C correctly shows these substitutions, with the ethyl group located on the 3rd carbon atom and the methyl group on the 4th carbon atom. The other choices either have substitutions in the wrong positions or have additional, extraneous atoms or groups.
