Question

through chlorine is an electron reductant agent but in substitution aromatic reactions,it directs Ortho and para position ,why ?​

Answer 1

The -I effect of chlorine withdraws electrons from the benzene ring. Hence tends to destabilize the intermediate carbocation formed during the electrophilic substitution. Conversely Cl donates its lone pair of electrons to the aromatic ring and hence increase the electron density at ortho and para positions.
