Ethylene dibromide ($1$,$2$-dibromoethane) on heating with metallic sodium in ether solution yields:

Which compound is formed when $CH_3OH$ reacts with $CH_3MgX$?

The suitable reagents for the conversion of methane into methyl iodide are

$RMgI$ when treated with ice-cold water liberated a gas which occupied $1.4 \text{ dm}^3/\text{g}$ at $STP$. The gas produced is further reacted with iodine in the presence of $HIO_3$ to give compound $(X)$. Compound $(X)$ in the presence of $Na$ and dry ether produced compound $(Y)$. The molar mass of compound $(Y)$ is . . . . . . $\text{g mol}^{-1}$. (Nearest integer)

When ethyl bromide and $n$-propyl bromide are allowed to react with $Na$ metal in dry ether,the number of different alkanes formed is

Give the mechanism of chlorination of methane.
