List of the following compound according to their reactivity towards electrophilic substitution.
Homework Answers
Generally Benzene and it's it's derivatives undergo Electrophilic substitution reactions. It needs more electron density on benzene ring. Donating groups increases the electron density hence more reactive.
Withdrawing group decreases the reactivity.
A. O-dibromo benzene> bromobenzene> benzene
B. P-methoxy benzonitrile> p-methylbenzonittrile> benzonitrile
C. O-xylene> fluorobenzene> Benzaldehyde
NO2 is a strong withdrawing group and decresdec the electron density on benzene ring hence further Electrophilic substitution doesn't occurs.

Consider the reactivity of phenol, bromobenzene, toluene, and nitrobenzene toward electrophilic aromatic substitution. 1.) The most reactive compound is (pick one: phenol, bromobenzene, toluene, and nitrobenzene) because the (pick one: electron donating or electron withdrawing) character of the (pick one: alcohol group, methyl group, bromine atom, or nitro group) increases the rate of the reaction. 2.) The least reactive compound is (pick one: phenol, bromobenzene, toluene, and nitrobenzene) because the (pick one: electron donating or electron withdrawing) character of the...
