How many different substituent groups can be obtained by removing a hydrogen atom from butane?
A) 1
B) 2
C) 3
D) 4

Question

Quizplus · Accepted Answer

Butane has two types of hydrogen atoms: those on the end carbons (which give the same substituent group when removed) and those on the middle carbons (which also give the same substituent group when removed). Removing a hydrogen from an end carbon yields an n-propyl group, while removing one from a middle carbon yields an isopropyl group, resulting in two different substituent groups.
