In Wurtz reaction,alkyl halides react with:

In commercial gasolines,the type of hydrocarbons which are more desirable is

The reaction conditions leading to the best yields of $C_2H_5Cl$ are

$R^{\prime}-X \xrightarrow{Na / \text{ether}} 2,3-\text{dimethylbutane}$. Identify $R^{\prime}$.

Iodination of a hydrocarbon $(C-H \rightarrow C-I)$ with molecular iodine is a slow and reversible reaction. However,it can be carried out in the presence of an oxidizing agent such as

Write the reactions for the preparation of ethane from the following:
$(i)$ Acetic acid $(CH_3COOH)$
$(ii)$ Methane $(CH_4)$
$(iii)$ Acetate ion $(CH_3COO^{-})$
