1,3-Dichlorobenzene (also known as meta-dichlorobenzene) is an
organic compound
In chemistry, organic compounds are generally any chemical compounds that contain carbon-hydrogen or carbon-carbon bonds. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. T ...

2. It is the least common of the three isomers of
dichlorobenzene There are three distinct chemical compounds which are dichlorobenzenes:
* 1,2-Dichlorobenzene or ''ortho''-dichlorobenzene;
*1,3-Dichlorobenzene or ''meta''-dichlorobenzene;
*1,4-Dichlorobenzene or ''para''-dichlorobenzene.
All three isomers are co ...
