Question
Among the following, the compound that can be most redily sulphonated is :
Options
A.benzene
B.nitrobenzene
C.toluene
D.chlorobenzene
Solution
Sulphonation is an E+ -substitution rection and any gp. which increases the e- -density on benzene ring, wil activate the benzene ring.
- CH3 is electron releasing gp. and thus toluene is more reactive than benzene in sulphononation reactions.
- NO2 and - Cl are de-activating group, thus nitrobenzene and chlorobenzene are less reactive than benzene.
