Question

Hydrolysis means a reaction with __________.

Options
  • A

    Oxygen

  • B

    Hydrogen

  • C

    Water

  • D

    Air  

Explanation

Hydro means water and lysis means to break. Hence hydrolysis involves a reaction in which water is used.

a) Oxygen

This option is incorrect. Hydrolysis is not a reaction with oxygen. Hydrolysis involves a chemical reaction with water molecules. 

b) Hydrogen

This option is incorrect. Hydrolysis is not a reaction with hydrogen. It involves a chemical reaction with water molecules. 

c) Water

This option is correct. Hydrolysis means a chemical reaction with water. In this process, a compound is broken down into its components through the addition of water molecules. Hydrolysis is a common reaction in organic and inorganic chemistry. 

d) Air

This option is incorrect. Hydrolysis is not a reaction with air. It involves a reaction with water molecules, not with the entire composition of air.
