Orbital interaction between the $\sigma$ bonds of a substituent group and a neighbouring $\pi$ orbital is known as

Which of the following statements are correct?
$(i)$ Inductive effect and resonance effect are possible in chlorobenzene.
$(ii)$ Resonance effect dominates over inductive effect in anisole.
$(iii)$ $p-$nitrobenzoic acid is less acidic than $m-$nitrobenzoic acid.
$(iv)$ Diphenylamine is more basic than aniline.

What is the order of $-I$ effect in orbitals?

The decreasing order of $-I$ (inductive) effect power for the given groups is:
$A. -CN$
$B. -NO_2$
$C. -NH_2$
$D. -F$

In $CH_3(3) - CH_2(2) - CH_2(1) - Cl$,give the increasing order of the inductive effect for carbon atoms $1, 2,$ and $3$.
