Solution

(a) The melting and boiling point of the successive members of the homologous series of alcohols increase with the increase in molecular mass.

(b) When ethanol reacts with acetic acid ethyl acetate is formed.

$C H_{3} - C O O H + C H_{3} - C H_{2} O H C o n c . H_{2} S O_{4} - ------- \to C H_{3} - C O O - C_{2} H_{5} + H_{2} O$

(c) This reaction is known as an esterification reaction.
