Question

Three types of intermolecular forces found in plastics are?

Option 1: Van der Waals forces, covalent bonds, and hydrogen bonding.
Option 2: Ionic bonding, metallic bonding, and covalent bonds.
Option 3: London dispersion forces, dipole-dipole interactions, and hydrogen bonding.
Option 4: Electrostatic forces, covalent bonds, and metallic bonding.

Answer 1

Option 3 is correct as the three types of intermolecular forces found in plastics are London dispersion forces, dipole-dipole interactions, and hydrogen bonding, which are considered van der Waals forces.

Step-by-step explanation:

The three types of intermolecular forces found in plastics are London dispersion forces, dipole-dipole interactions, and hydrogen bonding. These are collectively known as van der Waals forces. The correct option that lists these forces is Option 3: London dispersion forces, dipole-dipole interactions, and hydrogen bonding.

London dispersion forces are the weakest type of intermolecular forces and arise due to temporary fluctuations in electron density within a molecule, causing a temporary dipole that induces a dipole in adjacent molecules. Dipole-dipole interactions occur between molecules with permanent dipole moments, and their strength depends on the orientation and distance between the dipoles. Hydrogen bonding is a special type of dipole-dipole interaction that occurs when hydrogen is bonded to a highly electronegative atom like nitrogen, oxygen, or fluorine, resulting in a strong electrostatic attraction between molecules.
