1.	Out of benzene, m–dinitrobenzene and toluene which will undergo nitration most easily and why?
Answer» SOLUTION :Toluene. This is because `-CH_3`GROUP is an electron releasing (electron-donating) group and ACTIVATES the ring. On the other HAND, `-NO_2` group is an electron-withdrawing group and DEACTIVATES the ring. This is why toluene undergoes nitration most easily.
