When 2-bromo-2-methylpropane is treated with aqueous sodium hydroxide, 2-methylpropan-2-ol is formed. The reaction follows an $S_N1$ mechanism. How should the initial step in the mechanism be described?
- Aby a curly arrow from a lone pair on the $ ext{OH}^-$ ion to the $ ext{C}^{ +}$ atom of 2-bromopropane
- Bby a curly arrow from the $ ext{C-Br}$ bond to the $ ext{Br}$ atom
- Cby a curly arrow from the $ ext{C-Br}$ bond to the $ ext{C}$ atom
- Dby the homolytic fission of the $ ext{C-Br}$ bond
