As per the following options, what is the most suitable property of glycerol?
-
A.
It is insoluble in water
-
B.
It is hygroscopic
-
C.
It is a solid at room temperature
-
D.
It has a strong odor
Correct Answer:
B. It is hygroscopic
Explanation:
Glycerol is a trihydroxy sugar alcohol characterized by its strong affinity for water. Its chemical structure contains three hydroxyl groups, which allow it to form extensive hydrogen bonds with water molecules, making it highly hygroscopic. This means it readily attracts and absorbs moisture from the surrounding atmosphere. While pure glycerol has a melting point of approximately 18 degrees Celsius, it is typically encountered as a viscous, odorless liquid at room temperature and is completely soluble in water rather than insoluble.
