Sodium ethanoate on heating with soda lime gives '$X$'. Electrolysis of aqueous solution of sodium ethanoate gives '$Y$'. '$X$' and '$Y$' respectively are

The general formulas for alkene and alkane are respectively:

The number of possible constitutional isomers of an alkane with the formula $C_6H_{14}$ is:

Which reactions are difficult for alkanes?

Number of alkanes obtained on electrolysis of a mixture of $CH_3COONa$ and $C_2H_5COONa$ is $.....$.

Identify the initiation step$(s)$ $(X)$ and termination step$(s)$ $(Y)$ of free radical chlorination of $CH_4$ from the following:
$a) \dot{C}H_3 + \dot{Cl} \rightarrow CH_3-Cl$
$b) \dot{Cl} + \dot{Cl} \rightarrow Cl_2$
$c) \dot{C}H_3 + Cl_2 \rightarrow CH_3-Cl + \dot{Cl}$
$d) Cl_2 \rightarrow 2\dot{Cl}$
$e) CH_4 + \dot{Cl} \rightarrow \dot{C}H_3 + HCl$
$f) \dot{C}H_3 + \dot{C}H_3 \rightarrow CH_3-CH_3$
