2. hypochlorous acid

3. chlorine

4. hydrochloric acid

p-nitrophenol is stronger acid than phenol because nitro group is:

The correct order of the acidic strength for the above compounds is -

(I)	(II)	(III)

1. I > II > III                           

2. III > I > II

3. II > III > I                           

4. I > III > II

The boiling point of ethanol is higher than that of dimethyl ether due to the presence of
