Answer 1

Reactivity order for this reaction

Explanation:

• Option B is correct answer

• When alcohol react with $NaBr + H_{2} SO_{4}$ it undergoes substitution reaction and for Benzyl halide

• In this Reaction Carbocation is formed

• Carbocation is stabilized due to Electron donating group (EDG)

• $N(CH_{3} )_{2}$  has a more electron donating power than $CH_{3}$

• While $NO_{2}$ is a Electron withdrawing group. its reactivity in substitution is less then all the reactant

• In alcohol if this Group   $N(CH_{3} )_{2}$  attached show more reactivity towards this reaction
