CHM 102 Introductory Reaction Mechanism and Kinetics Objective Question

Question

Which of the following species is the most stable?
Options
A CH3• (methyl radical)
Correct Answer
B CH3+ (methyl carbocation)
C CH3- (methyl carbanion)
D Cannot compare different types
Correct Answer

Option A is the correct answer.

Detailed Explanation

Among the three, the methyl radical is relatively more stable compared to the extremely unstable methyl carbocation and carbanion, but each type has its own stability order. Generally, radicals are less reactive than carbocations/carbanions in many contexts, but the question likely expects CH3• as the most stable of the three at room temperature under normal conditions.

Hint

Radicals are neutral and less highly energetic.
