Intermolecular Forces

Front

What are intermolecular forces?

Back

Intermolecular forces are the forces of attraction or repulsion between neighboring particles (molecules, atoms, or ions). They play a crucial role in determining the physical properties of substances.

Front

What type of intermolecular force is present in CO₂?

Back

Dispersion Force.

Front

How is the polarity of a bond determined?

Back

The polarity of a bond is determined by the difference in the electronegativities of the two atoms involved.

Front

In a polar covalent bond, where do the electrons tend to gather?

Back

Mostly around the atom with the greatest electronegativity.

Front

What type of intermolecular force is present in Cl₂?

Back

Dispersion Force.

Front

What explains the high boiling point of water?

Back

Hydrogen bonding.

Front

Define hydrogen bonding.

Back

Hydrogen bonding is a strong type of dipole-dipole attraction that occurs between molecules when hydrogen is bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine.

Front

What are dispersion forces?

Back

Dispersion forces, also known as London dispersion forces, are weak intermolecular forces that arise from temporary shifts in electron density in atoms or molecules.

Front

What is the significance of electronegativity in determining bond polarity?

Back

Electronegativity is a measure of an atom's ability to attract shared electrons in a bond. The greater the difference in electronegativity between two atoms, the more polar the bond.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of chemical bond where a pair of electrons is unequally shared between two atoms, leading to a dipole moment.
