Question

Which of the following statements about noncovalent bonding interactions is NOT true?

Van der Waals interactions, also known as dispersion forces, are the weakest of the attractive noncovalent bonding interactions.
Charge-induced dipole interactions are inversely proportional to the square of the distance between the two atoms.
A charge may induce formation of a dipole in a nearby polarizable molecule.
All noncovalent bond interactions are inherently electrostatic in nature.

Answer 1

All of the statements about noncovalent bonding interactions are true except for the statement that all noncovalent bond interactions are inherently electrostatic in nature.

Step-by-step explanation:

All of the statements about noncovalent bonding interactions are true except for the statement that All noncovalent bond interactions are inherently electrostatic in nature. While most noncovalent interactions are indeed electrostatic in nature, van der Waals interactions, also known as dispersion forces, do not involve the electrostatic attraction between charged particles. Instead, van der Waals interactions are caused by temporary fluctuations in electron distribution that lead to the formation of induced dipoles and the subsequent temporary attraction between molecules. Therefore, the correct answer is the last statement.

Answer 2

For the non covalent bonding interaction the following statement is incorrect.

" Charge induced dipole interactions are inversely proportional to the sqaure of the distance between the two atoms"

because charge induced dipole interactions are directly proportional to the square of the distance between the two atoms.
