In the electrophilic substituion of benzene ring, the second substituent is directed by the group already present. Electron releasing groups (+I and +M) are ortho-para-directing and activating, whreas the electron withdrawing groups (-I and -M) are meta-directing and deactivating. Halogens are placed under the category of +T (Tautomeric) groups because they have -Ibdyctuve abd +Mesomeric effect. These groups are deactivating but ortho-para-directing. In the introduction of third group to the benzene ring, the product of minimum steric gindrance is formed. Answer the follwing questions : Ortho-Xylene on mono nitration givesA. two productsB. three productsC. one productsD. four products
