The reaction of methane with concentrated $HNO_3$ at high temperature yields .........

$n$-Propyl chloride reacts with sodium metal in dry ether to give:

In the bromination of isobutane,the relative reactivity rates of $1^oH, 2^oH,$ and $3^oH$ are $1 : 82 : 1600$ respectively. Calculate the percentage yield of products $(a)$ and $(b)$ in the following reaction:
$CH_3-CH(CH_3)-CH_3 (excess) + Br_2 \xrightarrow{hv} (a) CH_3-C(Br)(CH_3)-CH_3 + (b) CH_3-CH(CH_3)-CH_2Br$

Propane cannot be prepared from which reaction?

What is the number of moles of nascent hydrogen required to prepare $1$ mole of methane from iodomethane?

$CH_3Cl \to CH_4$
Above conversion can be achieved by
