When heated under reflux with an aqueous solution of sodium hydroxide, 2-bromo-2-methylpropane undergoes nucleophilic substitution. Which row is correct?
- A$\text{S}_\text{N}1$: the hydroxide ion is helped in its approach to the central carbon atom by the methyl groups
- B$\text{S}_\text{N}1$: the intermediate carbocation is stabilised by the inductive effect of the methyl groups
- C$\text{S}_\text{N}2$: the hydroxide ion is hindered in its approach to the central carbon atom by the methyl groups
- D$\text{S}_\text{N}2$: the intermediate carbocation is destabilised by the inductive effect of the methyl groups
