Long Answer TypeHow are alkanes formed from:
(i) unsaturated hydrocarbons
(ii) sodium salt of fatty acids?
Why is Wurtz reaction not preferred for the preparation of alkanes containing odd number of carbon atoms? Illustrate your answer bytaking one example.
Short Answer Type
Experiment: Powdered sodium acetate is mixed with four times the amount of soda lime. The mixture is taken in a hard glass tube. It is fitted with the delivery tube.
As the contents of the tube are heated, methane gas is produced. It is collected by the downward displacement of water.
