In the following reaction,$A$ is:

$C.N.G$ is........

In the Fischer-Tropsch synthesis of petrol,$.....$ and $.....$ are used as the raw materials.

Give the complete and incomplete combustion reactions of heptane and nonane.

The cycloalkane formed when $1,4$-dibromopentane is heated with sodium is:

Consider the isomers of the hydrocarbon with molecular formula $C_5H_{10}$. These isomers do not decolourise $KMnO_4$ solution. These isomers are subjected to chlorination with chlorine in the presence of light to give monochloro compounds. The total number of monochloro compounds (structural isomers only) formed from all these isomers is . . . . . . .
