Strong nucleophiles are VERY important throughout organic chemistry , but will be especially important when trying to determine the products of elimination and substitution ( SN1 vs SN2 ) reactions.
WebBulky nucleophiles have a hard time getting to the α -carbon, and thus increase the proportion of E2 to SN2. Polar, aprotic solvents increase nucleophilicity, and thus … WebJan 23, 2024 · In the S N 2 reaction, the nucleophile approaches the carbon atom to which the leaving group is attached.
