Answer 1

Answer:

The -I groups are involved in the electron withdrawing .so, its called as inductive effect . the examples of it are highly electronegative halogens -F,-Cl,-Br,-I,-NO2 etc

+I group there electronegative is less than hydrogen atom. -I group there electronegative is more than hydrogen atom. They decreases the electron density nearly atom. Eg NO2, CN, tertiary amine cation, halogen group
