Identify the correct order of reactivity in electrophilic substitution reaction of the following compounds.
(1) Benzene
(2) Toluene
(3) Chlorobenzene,
(4) Nitrobenzene.

Options

A. `AgtBgtCgtD`
B. `DgtCgtBgtA`
C. `BgtAgtCgtD`
D. `BgtCgtAgtD`

Answer

c

Explanation

More stronger the activating group, more will be electrophilic substitution reaction.
`-NO_(2)` groups is electron attraction group, so it deactivates the benzene ring largely `-Cl` atom also deactivates the benzene ring but this deactivation is lower to `-NO_(2)` group, while `-CH_(3)` GROUP ACTIVATES.
