Molecular Geometry & IMFs

Front

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.

Front

What are Intermolecular Forces (IMFs)?

Back

Intermolecular Forces are the forces of attraction or repulsion between neighboring particles (molecules, atoms, or ions) that affect the physical properties of substances.

How do lone pairs of electrons affect bond angles?

Back

Lone pairs decrease bond angles because they occupy more space than bonded electrons, squeezing the bonds within the molecule closer together.

Front

What is VSEPR theory?

Back

VSEPR stands for Valence Shell Electron Pair Repulsion, a model used to predict the geometry of individual molecules based on the repulsion between electron pairs.

Front

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

Back

The shape is tetrahedral.

Front

What are the two key factors that affect the polarity of a molecule?

Back

Asymmetry and lone pairs of electrons on the central atom.

Front

What is a polar molecule?

Back

A polar molecule has a net dipole moment due to the presence of polar bonds and an asymmetrical shape.

Front

What is a nonpolar molecule?

Back

A nonpolar molecule has no net dipole moment, often due to symmetrical shape or equal sharing of electrons.

Front

What is the bond angle in a tetrahedral molecule?

Back

The bond angle in a tetrahedral molecule is approximately 109.5 degrees.

Front

What type of bond is present in O₂?

Back

O₂ has a double bond.
