What is the Characteristic Functional Group of Thiols

Question

What is the characteristic functional group of thiols?
A) -NH
B) -OH
C) -PH
D) -SH

Accepted Answer

The characteristic functional group of thiols is -SH, which consists of a sulfur atom bonded to a hydrogen atom. It is a polar group that confers unique chemical properties to thiols, including their ability to form disulfide bonds and participate in redox reactions. The other options, -NH, -OH, and -PH, are functional groups for amines, alcohols, and phosphines, respectively.
