71. Arrange the following compounds in increasing order of boiling point and account for the order:
(a) 1-pentanol, (b) 2-methyl-2-butanol, (c) 3-methyl-butanol-2.

Why is ethanol less acidic than water?

Compare the acidity of Cl—CH₂ CH₂OH and CH₃CH₂OH. Explain.

Arrange the following in order of decreasing basic strength:
(CH₃)₃(CO^–, CH₃O^–, (CH₃)₂CHO^–

Compare and explain the relative Bronsted basicities of 1°, 2° and 3° alcohols in the liquid state.

Give one example of a reaction to show that alcohol acts as a Bronsted base.

What happens when ethanol reacts with Na metal? Name the products formed.

Arrange the following alcohols in order of increasing reactivity towards Na metal:

Explain why sodium (Na) may be used to remove the last trates of H₂O from benzene but not from ethanol?

Give the major product of the reaction of ethanol with:
(i) Ethanoic anhydride (CH₃CO)₂O.
(ii) Ethanol chloride in the presence of pyridine.
