Question 72: Intermolecular forces are forces of attraction and repulsion between interacting particles that will include :
A. dipole-dipole forces.
B. dipole – induced dipole forces.
C. hydrogen bonding.
D. covalent bonding.
E. dispersion forces.
Choose the most appropriate answer from the options given below :
(1) A, B, C, E are correct.
(2) A, C, D, E are correct.
(3) B, C, D, E are correct.
(4) A, B, C, D are correct.
Answer: Option (1)
Explanation:
Intermolecular forces are weak forces of attraction or repulsion that act between molecules or particles, not within a molecule.
Dipole-dipole forces act between polar molecules due to attraction between opposite charges of permanent dipoles.
Dipole-induced dipole forces occur when a polar molecule induces a temporary dipole in a nonpolar molecule, leading to attraction.
Hydrogen bonding is a strong type of intermolecular force that occurs when hydrogen is bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine.
Dispersion forces, also known as London forces, arise due to temporary fluctuations in electron density and are present in all molecules.
Covalent bonding is an intramolecular force that holds atoms together within a molecule and is not an intermolecular force.
Therefore, A, B, C, and E are intermolecular forces, making option (1) the correct answer.
