1.what is nucleophilic substitution reaction and nucleophilic addition reaction. 2.what is electrophilic substitution and addition reactions? (give me full explanation and difference between them with some example plz).
Nucleophilic substitution reaction:-The reactions in which a nucleophile substitutes another nucleophile are called as nucleophilic substitution reaction.For example,
CH3Br + OH- CH3OH + Br-
Nucleophilic addition reaction:-The reactions in which a nucleophile add to a given reactant are called as nucleophilic addition reaction.
H2C=CH2 + HBr BrH2C-CH3
Here Br- nucleophile is added to the given alkene.
