What is a hydrogen bond?

(a) The covalent bond between two hydrogen atoms

(b) A strong glue commonly found in hardware stores

(c) An unusually strong dipole-dipole attraction

(d) A type of nuclear explosive

To determine

The correct option for the statement “What is a hydrogen bond?”

Answer to Problem 10RAT

The correct option for the statement “What is a hydrogen bond?” is option (c).

Explanation of Solution

The dipole is the segregation of charges. It happens due to the difference in the values of electronegativities.

The dipole-dipole interaction is the interaction occurring between two polar molecules.

The dipole in polar molecules is because of the difference in values of electronegativities and it gives partial charges on existing atoms.

The hydrogen bonds exists between the molecules with hydrogen atom which is bonded to an atom with large electronegativity value.

It exists in molecules of water as. oxygen atom present is highly electronegative.

It is an unusually strong dipole-dipole interaction which keeps them bonded.

Conclusion:

Therefore, the correct option for the statement “What is a hydrogen bond?” is option (C).
