Question

How many molecules of water are released during the polymerization of a 20 monomer long cellulose molecule

Answer 1

Answer: 19 water molecules

Explanation:

Polymerization can be defined as the process by which monomers gets attached to one another to form a polymer. Example: ethene polymerize to form polyethylene.

Polymerization of 20 monomers of cellulose molecules releases 19 molecules of water.

Polymer bond is formed when -OH  group from the first monomers is attached to the H molecules of the second monomers.

For, 20 monomers there will be 19 water molecules released.

Answer 2

The polymerization of a 20 monomer-long cellulose molecule RELEASES 19 MOLECULES of water (H2O).

• Cellulose is a carbohydrate polymer composed of many glucose units (i.e., monomers) joined by glycosidic bonds.

• When a glycosidic bond is formed, a water (H2O) molecule is released.

• Thus, glycosidic bonds are formed by dehydration synthesis reactions.

• A cellulose molecule composed of 20 monomers of glucose contains 19 glycosidic bonds.

In conclusion, the polymerization of a 20 monomer-long cellulose molecule RELEASES 19 molecules of water (H2O).
