Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In a hydrolysis reaction, a large molecule becomes ____
A
even larger
B
two smaller molecules
C
two really large molecules
D
None of the above
Explanation: 

Detailed explanation-1: -A large molecule is split into smaller sections by breaking a bond, adding-H to one section and-OH to the other. The products are simpler substances. Since it involves the addition of water, this explains why it is called hydrolysis, meaning splitting by water.

Detailed explanation-2: -In a hydrolysis reaction, a larger molecule forms two (or more) smaller molecules and water is consumed as a reactant. Hydrolysis ("hydro” = water and “lysis” = break) involves adding water to one large molecule to break it into multiple smaller molecules.

Detailed explanation-3: -Hydrolysis is the breakdown of large molecules to form smaller molecules. Water molecules are used in this process.

Detailed explanation-4: -polymerization, any process in which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or network molecule, called a polymer.

Detailed explanation-5: -Types. Usually hydrolysis is a chemical process in which a molecule of water is added to a substance. Sometimes this addition causes both the substance and water molecule to split into two parts. In such reactions, one fragment of the target molecule (or parent molecule) gains a hydrogen ion.
