The more the basic character of the leaving group, the lesser is the reactivity. The basic character follows the order:

1. NH2− > OR− > RCOO− > Cl−
2. NH2− > RCOO− > OR− > Cl−
3. Cl− > NH2− > OR− > RCOO−
4. RCOO− > NH2− > Cl− > OR−

Correct answer: NH2− > RCOO− > OR− > Cl−

Solution

The basic character of a leaving group decreases in the order: NH2− > RCOO− > OR− > Cl−.
