Question

Quizplus · Accepted Answer

The compound has a trans configuration because the two substituents on the ring are on opposite sides. The largest substituent is the tert-butyl group, which has priority over the smaller isopropyl group. The numbering starts at the end closest to the tert-butyl group, giving the numbering 1-tert-butyl-2-methylcyclopentane. Since the two substituents are on opposite sides, it is trans-1-tert-butyl-2-methylcyclopentane.
