Electrophilic substitution on mono substituted benzene is determined by electronic effects +1, -M groups are ortho, para directors, where as -1,-M groups are meta directions. When there is a competition between inductive and mesomeric effects, the latter wins over. Electrophilic substitution on disubstituted benzene is determined by the combined effect of both groups. Usually activating group wins over deactivating group. When one of the groups has a lone pair of electrons, that will determine the product formation. Usually a third group will not enter the position in between the two existing groups due to steric reasons. Identify the incorrect statement

Answer»

Solvolysis of cholorobenzene is DIFFICULT but 2,4,6-trinitrochlorobenzene can be EASILY solvolysed
REACTIVITY of CHLOROBENZENE is more than benzene
p/o-ratio increases when host group is bulky
Toluene is more reactive than benzene

Solution :Reactivity of chlorobenzene is LESS than benzene
