WebNov 1, 2016 · Electrophile: In an S N 2 reaction, the nucleophile approaches the electrophile from the side opposite to the leaving group. This means that the three other groups attached to the reactive carbon in the electrophile face towards the nucleophile as it approaches. If these three groups are small (e.g., all H's), then the nucleophile can …

A solvent whose molecules do not have a hydrogen atom attached to a strongly electronegative element (such as oxygen). For most purposes, this means that an aprotic solvent is one whose molecules lack an -OH group.
WebIt is possible, however, for either reaction to being prevented by a very poor leaving group. A good leaving group will take electrons from its bond in order to leave, so it needs to be highly electronegative. Electronegative species attract electrons more readily, especially those from bonded pairs. Cl–, Br–, I–, and H2O are among the ... WebThis problem has been solved!
