Question

Which of the following represent the correct
order of decreasing reactivity?​

Answer 1

Answer:

The order of decreasing reactivity towards electrophilic reagent is d>b>a>c or Anisole > toluene > benzene > chlroro benzene.

The correct increasing order of reactivity is I < IV < II < III. This is because greater is the electron density on aromatic ring, greater is the reactivity towards electrophilic aromatic substitution.

Answer 2
