Front

What is the geometry of a molecule represented as AB4?

Back

Tetrahedral.

Front

Define 'linear' molecular geometry.

Back

A molecular shape where atoms are arranged in a straight line.

Front

What is 'bent' molecular geometry?

Back

A shape where the molecule has a central atom with two bonded pairs and one or more lone pairs.

Front

What does 'trigonal pyramidal' mean in molecular geometry?

Back

A shape with a central atom bonded to three other atoms and one lone pair.

Front

What is the significance of lone pairs in determining molecular shape?

Back

Lone pairs occupy space and can affect the angles between bonded atoms.

Front

How does the presence of lone pairs affect bond angles?

Back

Lone pairs can compress bond angles between bonded atoms.
