Can Sn2 Happen On A Tertiary Carbon?

Can Sn2 Happen On A Tertiary Carbon? Can sn2 happen on a tertiary carbon? nucleophilic substitutions Why do tertiary carbons not undergo SN2? The reaction of hydroxide ion with chloromethane occurs in a single step. Alkyl substituents decrease the rates of SN2 reactions by interfering with the approach of the nucleophile. In 1-bromo-2,2-dimethylpropane, steric hindrance
