Answer:
In the communication process, a medium is a channel or system of communication—the means by which information (the message) is transmitted between a speaker or writer (the sender) and an audience (the receiver). The plural form is media, and the term is also known as a channel.
Kolbe 's Reaction :-
The Kolbe–Schmitt reaction or Kolbe process (named after Hermann Kolbe and Rudolf Schmitt) is a carboxylation chemical reaction that proceeds by heating sodium phenoxide (the sodium salt of phenol) with carbon dioxide under pressure (100 atm, 125 °C), then treating the product with sulfuric acid.
Perkin 's Method :-
The Perkin reaction gives an alpha, beta-unsaturated aromatic acid via the aldol condensation of an aromatic aldehyde and an acid anhydride. The alkali salt of the acid is also present. This alkali salt acts as a base catalyst. Other bases can be used instead of the alkali salt of the acid in the Perkin reaction.
