If 16.0 g of methanol are reacted with an excess of PBr3, how many grams of CH3Br would be formed if there is a 25.0% yield
Why E2 is favored over SN2, Sn2 requires a strong nucleophile while E2 requires a strong base. But relatively compared if you have a very strong base the E2 is preferred. Why is it so?
