What is a nucleophilic substitution?

Answer 1

Nucleophilic substitution is the reaction of an electron pair donor (the nucleophile) with an electron pair acceptor (the electrophile).

The most general form for the reaction may be given as

Nuc: + R-LG → R-Nuc + LG:

The electron pair (:) from the nucleophile(Nuc) attacks the substrate (R-LG) forming a new bond, while the leaving group (LG) departs with an electron pair.

Answer 2

A nucleophilic substitution is a type of chemical reaction where a nucleophile displaces a leaving group from a substrate molecule. This substitution typically occurs at an electrophilic center, resulting in the replacement of one group by another. Nucleophilic substitutions are commonly encountered in organic chemistry and can proceed via different mechanisms such as SN1 (substitution nucleophilic unimolecular) and SN2 (substitution nucleophilic bimolecular).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
