Web12 Apr 2024 · Nucleophilic substitution reactions are of two types; substitution nucleophilic bimolecular (S N 2) and substitution nucleophilic unimolecular (S N 1) depending on molecules taking part in determining the rate of reaction. Web5 Apr 2024 · The nucleophile attacks the positively charged area of a compound or atom. A nucleophilic substitution reaction is a reaction that involves the replacement of one functional group or atom with another negatively charged functional group or atom. SN1 is a unimolecular reaction while SN2 is a bimolecular reaction. SN1 involves two steps.
