[Olympiad] Which mechanism describes the reaction of 2-bromo-2-methylpropane with aqueous NaOH?
Sₙ1
Sₙ2
E1
Addition
📝 Detailed explanation
2-bromo-2-methylpropane is a tertiary alkyl halide. Tertiary substrates favor the Sₙ1 mechanism because they form stable carbocations and are too sterically hindered for Sₙ2.
