# What element do all organic compounds contain?

Aug 1, 2017

All organic compounds contain carbon, as well as hydrogen, unless it has been replaced by another element.

#### Explanation:

Methane, $\text{CH"_4}$, is the simplest organic compound.

The hydrogen atoms in methane can be replaced by other elements.

${\text{CH"_4" + 2Cl}}_{2}$$\rightarrow$$\text{CCl"_4}$

Methane plus chlorine produces carbon tetrachloride, or tetrachloromethane. Even though carbon tetrachloride does not have hydrogen, it is still organic. Carbon tetrachloride is an organic solvent.
