Question

Glycerol is also known as

• A. trihydroxy propane
• B. dihydroxy propane
• C. tetrahydroxy propane
• D. monohydroxy propane

Answer 1

The correct option is A trihydroxy propane

Glycerol is an alcohol with three carbon atoms, five hydrogen atoms and three hydroxyl groups. Because of the presence of three hydroxyl groups, it is called trihydroxy. Propane is a three carbon alkane with the molecular formula C${}_3$H${}_8$. When three hydrogen atoms of propane are replaced by three hydroxyl groups, this gives rise to a molecule of glycerol.
