a) Complete the following reaction : b) Explain the following: i) Estenfication ii) Williamson Synthesis

Question

a) Complete the following:

b) Explain the following:

i) Estenfication

ii) Williamson Synthesis

Answer 1

b) i) Esterification – Alcohols and phenols react with carboxylic acids, and acid anhydrides in presence of small amount of concentrated sulphuric acid and with acid chlorides in presence of pyridine to form esters. This reaction is known as estenfi cation.

Or, 

any of the following chemical equations:

ii) Wihiamson synthesis – When and alkyl halide is treated with sodium alkoxide ether is formed. It is an important laboratory method for the preparation of symmetrical and unsymmetrical ethers.

Or, 

the chemical equation:

R-X + R’ – ONa → R-O-R’ + NaX

Or, any other specific example.
