Can Tertiary Carbons Undergo SN2?

Can Tertiary Carbons Undergo SN2? Here’s another tenet of organic chemistry that can be crossed out of the textbooks: Tertiary carbons can’t undergo bimolecular nucleophilic substitutions, also known as SN2 reactions. Why can SN2 happen on a tertiary carbon? Quick N’ Dirty Rule #2: If the substrate is tertiary, we can rule out SN2, because
