mercaptan – מילון אנגלי-אנגלי
mercaptan
n.
any of a class of foul-smelling chemical compounds which contain sulfur (Chemistry)
Thiol
In organic chemistry, a
thiol (, ) is an
organosulfur compound that contains a carbon-bonded
sulfhydryl (–C–SH or R–SH) group (where R represents an alkane, alkene, or other carbon-containing group of atoms). Thiols are the sulfur analogue of
alcohols (that is, sulfur takes the place of oxygen in the hydroxyl group of an alcohol), and the word is a
portmanteau of "thion" + "alcohol," with the first word deriving from
Greek θεῖον ("thion") = "sulfur." The –SH functional group itself is referred to as either a
thiol group or a
sulfhydryl group.

Mercaptan
(n.)
Any one of series of compounds, hydrosulphides of alcohol radicals, in composition resembling the alcohols, but containing sulphur in place of oxygen, and hence called also the sulphur alcohols. In general, they are colorless liquids having a strong, repulsive, garlic odor. The name is specifically applied to ethyl mercaptan, C2H5SH. So called from its avidity for mercury, and other metals.
