Strongest conjugate base is

Strongest conjugate base is
  1. $\mathrm{Cl}^{-}$
  2. $\mathrm{Br}^{-}$
  3. $I^{-}$
  4. $\mathrm{F}^{-}$

Solution

An acid loses a proton to form an anion known as its conjugate base. A strong acid will form a weak conjugate base and a weak acid will form a strong conjugate base. HF is a weak acid because it dissociates partially in water. So, it will form a strong conjugate base $\mathrm{F}^{-}$.
