Normal butane is converted into isobutane by:

Name the hydrocarbon that is a liquid at $STP$.

The conversion of $CH_4$ to $CH_3Cl$ is an example of which of the following reactions?

The number of isomeric products formed by the monochlorination of $2$-methylbutane in the presence of sunlight is . . . . . .

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

How many carbon atoms does an alkane (not a cycloalkane) need before it is capable of existing in an enantiomeric form?
