Answer:
d. sodium t-butoxide + bromomethane
Step-by-step explanation:
Sodium t-butoxide is a strong base with the chemical formula (CH3)3CONa and it is a non-nucleophilic base while bromomethane with the chemical formula CH3Br.
They both together gives 2-ethoxypropane (C5H12O).
(CH3)3CONa + CH3Br => C5H12O + NaBr
Hence, the correct option is "d".
