Among the following, which ion exhibits the least basic nature?

1. Chloride ion (Cl−)
2. Hydroxide ion (OH−)
3. Amide ion (NH2−)
4. Carboxylate ion (RCOO−)

Correct answer: Chloride ion (Cl−)

Solution

Cl− is the weakest base because it is the conjugate base of a strong acid (HCl), making it highly stable and less likely to accept protons.
