A more highly substituted carbocation is known to form more rapidly than less substituted carbocations (A), and is typically more stable (D). Additionally, it typically forms products more rapidly than less substituted carbocations (B). However, the activation energy required to form a more highly substituted carbocation is typically higher than that required for less substituted carbocations, meaning that the ΔG^± is typically smaller for less substituted carbocations (C is false). Therefore, choice C does not characterize a more highly substituted carbocation.
