Verified Answer
Identify the correct order of reactivity in electrophilic substitution...
−CH3 is an activating group because +I effect, −cl and −NO2 are deactivating due to their −I and −M effect.
∴ the option is 2>1>3>4

Identify the correct order of reactivity in electrophilic substitution...
The correct order of reactivity in electrophilic substitution reactions of the given compounds is 2134.
Explanation:
1. Benzene:
Benzene is the least reactive compound among the given options. It undergoes electrophilic substitution reactions, but at a slower rate compared to the other compounds. This is due to the high electron density of benzene resulting from its delocalized pi electron system. The pi electrons in benzene act as a nucleophile and repel electrophiles, reducing the reactivity.
2. Methylbenzene (Toluene):
Methylbenzene is more reactive than benzene due to the presence of an electron-donating methyl group (-CH3). The methyl group increases the electron density on the benzene ring, making it more nucleophilic and facilitating electrophilic substitution reactions.
3. Chlorobenzene:
Chlorobenzene is more reactive than methylbenzene because the chlorine atom is an electron-withdrawing group (-Cl). The chlorine atom withdraws electron density from the benzene ring, making it less nucleophilic and more susceptible to electrophilic attack.
4. Nitrobenzene:
Nitrobenzene is the most reactive compound among the given options. The nitro group (-NO2) is a strong electron-withdrawing group. It withdraws significant electron density from the benzene ring, making it highly susceptible to electrophilic attack. The presence of the nitro group also enhances the reactivity by stabilizing the positive charge on the electrophile.
In summary, the order of reactivity in electrophilic substitution reactions is as follows:
Benzene < methylbenzene="" />< chlorobenzene="" />< />
Please note that the reactivity order can vary depending on the specific reaction conditions and the nature of the electrophile involved.
