VSEPR Molecular Shapes and Bond Angles

Front

What are bond angles in molecular geometry?

Back

Bond angles are the angles formed between three atoms in a molecule, specifically the angle between two adjacent bonds. Common bond angles include <90°, <120°, and 180°.

Front

What is the bond angle for a tetrahedral molecular shape?

Back

The bond angles in a tetrahedral molecular shape are approximately 109.5°.

Front

What is the bond angle for a linear molecular shape?

Back

The bond angle for a linear molecular shape is 180°.

Front

What is the molecular shape of a molecule with four bonding pairs and no lone pairs?

Back

The molecular shape is tetrahedral.

Front

What is the molecular shape of a molecule with two bonding pairs and no lone pairs?

Back

The molecular shape is linear.

Front

What is the bond angle for a trigonal planar molecular shape?

Back

The bond angles in a trigonal planar molecular shape are approximately 120°.

Front

What is the molecular shape of a molecule with three bonding pairs and one lone pair?

Back

The molecular shape is trigonal pyramidal.

Front

What is the effect of lone pairs on bond angles?

Back

Lone pairs repel more strongly than bonding pairs, which can reduce bond angles between bonding pairs.

Front

What is the bond angle for a molecule with two lone pairs and two bonding pairs?

Back

The bond angle is approximately 104.5°, as seen in water (H2O).

Front

What is the molecular shape of a molecule with five bonding pairs?

Back

The molecular shape is trigonal bipyramidal.
