What is molecular geometry?

Back

Molecular geometry refers to the three-dimensional arrangement of atoms within a molecule, which influences its physical and chemical properties.

What is the molecular geometry of a molecule with four bonded atoms and no lone pairs?

Back

Tetrahedral.

Front

What are intermolecular forces?

Back

Intermolecular forces are 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 is the strongest type of intermolecular force?

Back

Hydrogen bonding is the strongest type of intermolecular force, but London dispersion forces (LDF) are the weakest.

Front

What is an ideal gas?

Back

An ideal gas is a theoretical gas composed of many particles that are in constant random motion and do not interact with each other, except during elastic collisions.

Front

What is the significance of the statement 'ideal gases experience completely inelastic collisions'?

Back

This statement is NOT true; ideal gases experience elastic collisions, meaning no kinetic energy is lost.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

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, resulting in a molecule with a slight electrical dipole moment.

Front

What type of bonding is found in water (H2O)?

Back

Water contains polar covalent bonding.

Front

What is a substance that contains both ionic and covalent bonds?

Back

Sodium hydroxide (NaOH) contains both ionic and covalent bonds.
