Which type of hybridization is found in the $C-C$ single bond of an alkane and the $C=C$ double bond of an alkene?

Assertion $(A):$ Sodium acetate on Kolbe's electrolysis gives ethane.
Reason $(R):$ Methyl free radical is formed at cathode.

What does petroleum mainly consist of?

The product obtained by the vapor phase nitration of propane is:

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

Photochemical chlorination of an alkane is initiated by a process of
