Consider the following statements
I) Hyperconjugation helps in increasing electron density at ortho an para sites in case of alkyl groups
II) Electron donating groups are activators and are ortho and para directors because they stabilize the arenium cations.
III) Electron withdrawing groups are activators and are meta directors because they stabilized the arenium cations.
IV) Halogens are activators and ortho and para directors.
Select correct statements.
