Question

The general formula ${\mathrm{C}}_{\mathrm{n}}{\mathrm{H}}_{2\mathrm{n}+2}$ represents ___.

• A. alkanes
• B. alkenes

Answer 1

Hydrocarbons are organic compound that contains Carbon $\left(\mathrm{C}\right)$ and Hydrogen $\left(\mathrm{H}\right)$ atoms.

Alkane is a saturated hydrocarbon that has Carbon-Carbon and Carbon-Hydrogen atoms that are only connected through single bonds.

The general formula of an alkane is ${\mathrm{C}}_{\mathrm{n}}{\mathrm{H}}_{2\mathrm{n}+2}$.

Where, $\mathrm{n}$ is the number of Carbon atoms in alkane compound and $2\mathrm{n}+2$ tells about the number of Hydrogen atoms in alkane compound.

Hence, the general formula ${\mathrm{C}}_{\mathrm{n}}{\mathrm{H}}_{2\mathrm{n}+2}$ represents alkanes.
