Molecular Geometry and Polarity Practice

Front

What is molecular geometry?

Back

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

Front

What determines the polarity of a molecule?

Back

The polarity of a molecule is determined by the difference in electronegativity between the bonded atoms and the molecular geometry.

Front

Define polar molecule.

Back

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

Front

Define nonpolar molecule.

Back

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

Front

What is the bond angle in a tetrahedral molecular geometry?

Back

The bond angle in a tetrahedral molecular geometry is approximately 109.5°.

Front

What is the bond angle in a trigonal planar molecular geometry?

Back

The bond angle in a trigonal planar molecular geometry is 120°.

Front

What is the bond angle in a linear molecular geometry?

Back

The bond angle in a linear molecular geometry is 180°.

Front

What is the molecular geometry of water (H2O)?

Back

The molecular geometry of water (H2O) is bent due to the two lone pairs on the oxygen atom.

Front

What is the molecular geometry of ammonia (NH3)?

Back

The molecular geometry of ammonia (NH3) is trigonal pyramidal due to one lone pair on the nitrogen atom.

Front

What is the molecular geometry of carbon dioxide (CO2)?

Back

The molecular geometry of carbon dioxide (CO2) is linear.
