WebApr 7, 2016 · Nucleophile: SN1 Reactions: SN 1 reactions require weak nucleophiles; they are neutral solvents such as CH 3 OH, H 2 O, and CH 3 CH 2 OH. SN2 Reactions: SN 2 reactions require strong nucleophiles. In other words, they are negatively charged nucleophiles such asCH 3 O –, CN –, RS –, N 3– and HO –.
WebA molecule’s steric hindrance can be used to favor a specific reaction. For example, there are two types of substitution reactions, Sn1 and Sn2. Both of these reactions can be performed with simple molecules; however, Sn1 can occur with bulky molecules, while Sn2 cannot because it is too congested for the mechanism known as a ‘backside attack’. chi wah online bookingWebthe strength of the nucleophile does not effect the rate of an SN1 reaction, but it does an SN2 reaction.
