Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the name given to the opposite process of condensation polymerisation?
A
neutralisation
B
addition
C
hydrolysis
Explanation: 

Detailed explanation-1: -Hydrolysis is the opposite to condensation. 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.

Detailed explanation-2: -hydrolysis definition. A chemical reaction in which water is used to break down a compound; this is achieved by breaking a covalent bond in the compound by inserting a water molecule across the bond. The opposite of this is a dehydration-condensation reaction.

Detailed explanation-3: -Polymers are broken back down into their monomers by the opposite type of reaction, called a hydrolysis reaction. A hydrolysis reaction involves adding a water molecule in order to break the bond between the monomers.

Detailed explanation-4: -Hydrolysis reactions are the reverse of condensation reactions. In a hydrolysis reaction, a larger molecule forms two (or more) smaller molecules and water is consumed as a reactant.

Detailed explanation-5: -Hydrolysis reactions can be the reverse of a condensation reaction in which two molecules join into a larger one and eject a water molecule. Thus hydrolysis adds water to break down, whereas condensation builds up by removing water.
