8.6. Assessing SN1, SN2, E1, E2: Which will happen?
WebA good base is usually a good nucleophile. So, strong bases — substances with negatively charged O, N, and C atoms — are strong nucleophiles. Examples are: RO⁻, OH⁻, RLi, … The general idea is that "poor" leaving groups have a strong nucleophilicity, or a … In general, an elimination reaction (specifically, it's called #beta# … WebSN2 reactions require good nucleophiles. Therefore a good nucleophile that is a weak base will favor SN2 while a weak nucleophile that is a strong base will favor E2. Bulky nucleophiles have a hard time getting to the α -carbon, and thus increase the … it fell on the floor
