Question

True or False?

e. Benzoic acid is more reactive than benzene toward electrophilic aromatic substitution

f. para-chlorobenzoic acid is more acidic than para-methoxybenzoic acid

g. A vinyl group is a meta director

h. para-nitroaniline is more basic than para-chloroaniline

Answer 1

e. Benzoic acid is more reactive than benzene toward electrophilic aromatic substitution : False

-COOH is a electron with drawing group. so that presence of -COOH decreases. reactivity of benzene ring towards electrophilic substitution.

f. para-chlorobenzoic acid is more acidic than para-methoxybenzoic acid : True

halo group is electron withdrawing group.so that acidity increases, nut now -OCH3.

g. A vinyl group is a meta director : true

h. para-nitroaniline is more basic than para-chloroaniline : false

-NO2 is strong electron withdrawing group.so that basicity decreases.
