Thiols are sulfur analogs of alcohols and are also called mercaptans. Sulfides are sulfur analogs of ethers and are also known as thioethers. Thiols and sulfides have lower boiling points and are less soluble in water than other alcohols and ethers. They also show little association through hydrogen bonding. Common thiols include those that give onions and garlic their smell, while common sulfides include metal sulfides like silver sulfide, mercury sulfide, and lead sulfide. Thiols and sulfides are used in industries like oil, gas, pulp and paper.
