A)​the methyl group.
B)​the ethyl group.
C)​the propyl group.
D)​the tert-butyl group.

Quizplus · Accepted Answer

The tert-butyl group is the most stable carbocation due to the presence of three methyl groups, which provide significant electron density and stabilize the positive charge. Therefore, the positive charge is most likely to stay on the tert-butyl group when the molecular ion of 2,2-dimethylpentane fragments.
