Concept introduction:
Electrophiles are electron-deficient species, which has positive or partially positive charge. Lewis acids are electrophiles, which accept electron pair.
Nucleophiles are electron-rich species, which has negative or partially negative charge. Lewis bases are nucleophiles, which donate electron pair.
Substitution reaction: A reaction in which one of the hydrogen atoms of a hydrocarbon or a
Nucleophilic substitution reaction is a reaction in which an electron-rich nucleophile attacks the positive or partial positive charge of an atom or a group of atoms to replace a leaving group.
In
The nucleophilic substitutions in which a nucleophile replaces a leaving group are known as
In an alkyl halide, the reaction takes place between halogen atoms and
The primary carbon atom is the one in which the required carbon atom is attached to only one other carbon atom. It is denoted by
The secondary carbon atom is the one in which the required carbon atom is attached to two other carbon atoms. It is denoted by
The tertiary carbon atom is the one in which the required carbon atom is attached to three other carbon atoms. It is denoted by
