Answer the following question given this paragraph: 

Thiols (also called mercaptans), which are sulfur analogs of alcohols, have the general formula RSH. Methanethiol (also called methyl mercaptan), has the formula CH3SH. Ethanethiol (ethyl mercaptan) is the most common odorant for liquid propane (LP) gas. The mild oxidation of thiols gives compounds called disulfides.

 Choices:

- carbonates

- halides
