The decreasing order of reactivity towards electrophilic substitution of the following compounds is
- A \(1>3>4>2\)
- B \(4>1>3>2\)
- C \(4>1>2>3\)
- D \(1>4>3>2\)
Answer & Solution
Correct Answer
(C) \(4>1>2>3\)
Step-by-step Solution
Detailed explanation
Due to \(+I\)-effect of \(-\mathrm{CH}_{3}\) group (4) has higher electron density, than benzene (1). Due to strong \(-I\)-effect of - Cl group and strong \(-I\) and \(-M\)-effect of \(-\mathrm{NO}_{2}\) group, both (2) and (3) have lower electron density, than benzene (l). As -…
