Question

All of the following interactions occur between antigen-antibody reaction except .................

• A. Ionic bond
• B. Covalent bond
• C. Hydrogen bond
• D. Vander waal force

Hint:

Antigen-antibody interactions are driven by weak, reversible forces such as ionic bonds, hydrogen bonds, and Van der Waals forces, but not by covalent bonds.

Answer 1

The Correct Option is B

Antigen-antibody interactions are generally mediated by weaker, non-covalent forces that allow for reversible binding between the antigen and antibody.
(1) Ionic bond: Ionic bonds play a role in antigen-antibody interactions. These are electrostatic interactions between charged groups on the antigen and antibody.
(2) Covalent bond: This is the correct answer. Covalent bonds are not typically involved in antigen-antibody interactions as these interactions rely on weaker, reversible forces such as ionic, hydrogen, and Van der Waals forces.
(3) Hydrogen bond: Hydrogen bonds are important in antigen-antibody interactions and occur between hydrogen atoms and electronegative atoms like oxygen or nitrogen.
(4) Van der Waals force: Van der Waals forces contribute to antigen-antibody binding, as they involve the attraction between nonpolar molecules or parts of molecules.
Conclusion: The correct answer is Option 2: Covalent bond as covalent bonds are not typically involved in antigen-antibody reactions.
