Solution

The correct option is B $C_{n} H_{2 n + 2}$
Alkanes are carbon chain compounds which has only single bonds in them. Its general formula is $C_{n} H_{2 n + 2}$ . Since only single bonds are present, every carbon will be either attached to another carbon atom and 3 hydrogen atoms or two carbon atoms and 2 hydrogen atoms.
