Two compounds, A and B, have the following properties:
(a) Both A and B have the formula C5H11Br.
(b) Both A and B are achiral.
(c) Compound A does not undergo elimination reactions when treated with strong bases.
(d) Compound A does not undergo nucleophilic substitution reactions under normal conditions.
(e) Compound B reacts rapidly with water at room temperature to give an alcohol with the formula C5H12O as the major product.
(f) Compound B reacts with potassium ethoxide to give hydrocarbon C with the formula C5H10 as the major product. Compound B reacts with potassium tert-butoxide to give hydrocarbon D, which is an isomer of hydrocarbon C, as the major product.
