Thanks! re4/2/2016 04:5S PM 82.4/100 Due Date: Points Pos Grade Cate Substit on an aromatic ring can have several effects on electrophilic nts can activate or deactivale the ring fo substitution, reactions or and direct sub From the are written as -X)Y property. The X is the atom directly bound to the aromatic ring. Activation of the ring You can check substitution up on any quest You can keep try you get it right o There is no penal .CN OH -COOH -NHCOCH COOH CH -NO2 .SOH ocOCH O Help With This O Web Help & Vi O T

Explanation / Answer

a) Apart from halogens, all the substitutuents having lone pair of electrons on the atom directly attached to the benzene ring activate it towards electrophillic substitution.

So, -NHCOCH3 and -OCOCH3shall be selected in the first column.

b) All the substitutuents having multiple bonds(no lone pair) on the atom directly attached to the benzene ring withdraw electron density from the ring through resonance.

So, -COOH and -SO3H shall be selected here.

c) All the substitutuents having lone pair of electrons on the atom directly attached to the benzene ring and alkyl group donate electrons through resonance or hyperconjugation and increase the electron density at ortho and para positions hence are ortho para directing groups.

So, -NHCOCH3 , -CH3 and -F shall be selected here.
