Carbocation formation is more favored with allylic or benzylic leaving groups than for the formation of typical alkyl cations because the vinyl or benzyl group is able to release electrons by resonance to stabilize the carbocation. For this reason, allylic and benzylic alkyl halides are ideal substrates for the SN1 mechanism.

The WikiPremed MCAT Course is a free comprehensive course in the undergraduate level general sciences. Undergraduate level physics, chemistry, organic chemistry and biology are presented by this course as a unified whole within a spiraling curriculum.
