$LPG$ mainly consists of the following:

Write about the Wurtz reaction or describe the preparation of alkanes from alkyl halides via the Wurtz reaction,including examples and its limitations.

The provided image shows a chemical reaction: $R' - X \xrightarrow{Na / \text{ether}} ?$. This is the Wurtz reaction. Identify the product formed in this reaction.

Assertion : $CH_4$ does not react with $Cl_2$ in dark.
Reason : Chlorination of $CH_4$ takes place in sunlight.

Determine the structure and name of $A$ and $B$ in the following reaction sequence:
$(A)$ $\xrightarrow{NaOH, -H_2O} (B)$ $\xrightarrow{NaOH, CaO, \Delta} CH_3CH_3$

$CH_3-CH(CH_3)-CH_2-CH_3 \xrightarrow[hv]{Cl_2} (x)$. Find the number of monochloro products including stereoisomers.
