The order of leaving group ability is :

1.	The order of leaving group ability is :
Answer» `(i) gt (II) gt (iii) gt (iv)` `(iv) gt (iii) gt (i) gt (ii)` `(iii) gt (ii) gt (i) gt (iv)` `(ii) gt (iii) gt (iv) gt (i)` Solution :Weaker the base, better is the leaving GROUP. ACIDITY : `F_3 C - SO_3 H gt MeSO_3 H gt AcOH gt MeOH`. Basicity : `underset (iv) (F_3)C^(Ө) lt underset (iii) MeSO_3^(Ө) lt underset (i) ACO^(Ө) lt underset (ii) MeO^(Ө)` Leaving group : `(iv) gt (iii) gt (i) gt (ii)`.
