Arrange the compounds in order of decreasing acidity :

(1) $C l - {C H}_{2} - {C H}_{2} - S H$

(2) ${C l}_{2} C H - {C H}_{2} - S H$

(3) $C l - {C H}_{2} - {C H}_{2} - O H$

(4) ${C H}_{3} - {C H}_{2} - O H$

Thiols are more acidic than the corresponding alcohols as their conjugate base is more stable due to the presence of d-orbitals in sulphur.

Presence of electron withdrawing groups will increase acidity.
