Which of the following statements are correct?a) +I group stabilizes a carbocationb) + I group stabilizes a carbanionc) - I group stabilizes a carbocationd) - I group stabilizes a carbanion

Stability order:–IE groups increases the stability of carbanion.As the no of -IE [Alkyl groups] groups increasestability of carbanion increases,Stability order:+IE group increases the electron density on carbanion carbon and hence decreases the stability of carbanion.→ As the no of +IE groups increases stability of carbanion decreases.Stability order:–IE groups increases the positive charge on carbocation carbonand hence decreases the stability of carbanion.→ As the no –IE groups increases stability of carbocation decreases.
