Question

What's true of non-covalent interactions?

Much of organic chemistry and inorganic chemistry is concerned with covalent, ionic, and metallic bonding, whereas non-covalent bonding is often given cursory treatment. Which of the following statements are TRUEabout the importance of non-covalent interactions?

Check all that apply.

Check all that apply.

Non-covalent interactions are rarely used in biological processes.

Non-covalent interactions include hydrogen bonding, dipole-induced dipole interactions, and London dispersion forces.

Non-covalent interactions are readily reversible.

Non-covalent interactions are too weak to support tight binding of a molecule to a protein.

Non-covalent interactions are relatively weak forces.

Answer 1

1. First statement is wrong. We come across them in all the biological systems like DNA, Proteins etc.

2. The second statement is correct. Non-covalent interactions include hydrogen bonding, dipole-induced dipole interactions, and London dispersion forces.

3. This statement is true.  Non-covalent interactions are readily reversible.

4. This statement is false. Non-covalent interactions are larger in number and hence are quite strong enough to support tight binding of a molecule to a protein.

5. This statement is true. Non-covalent interactions are relatively weak forces as compared to ionic, covalent and metallic bonding.
