323175 Read the Assertion and Reason carefully to mark the correct option out of the options given below.
Assertion :
Alcohols react both as nucleophiles and electrophiles.
Reason :
Alcohols react with active metals such sodium,potassium and aluminium to yeild corresponding alkoxides and liberate hydrogen.

323176 Which of the following statements are correct regarding esterification of alcohols?
I. Alcohols react with carboxylic acids, acid chlorides, and acid anhydrides to form esters.
II. The reaction with carboxylic acid and acid anhydride is carried out in presence of a small amount of conc. \(\mathrm{H}_{2} \mathrm{SO}_{4}\).
III. The reaction with acid chloride is carried out in presence of a base (pyridine) to neutralize the side product HCl .
IV. The reaction with carboxylic acid and acid anhydride is reversible while with acid chloride, it is irreversible.
