Test Unit 3 (3.7)

Front

What is a lone pair?

Back

A pair of non-bonding electrons.

Front

What is the shape of a molecule with a trigonal pyramidal geometry?

Back

Trigonal pyramidal.

Front

Which molecule has a linear shape?

Back

CO₂.

Front

What does VSEPR theory predict?

Back

Molecular Shape.

Front

How many lone pairs are in a molecule with 2 lone pairs?

Back

2.

Front

Define VSEPR theory.

Back

Valence Shell Electron Pair Repulsion theory; it predicts the shape of molecules based on electron pair repulsion.

Front

What is the molecular shape of CH₄?

Back

Tetrahedral.

Front

What is the difference between bonding and non-bonding electrons?

Back

Bonding electrons are involved in chemical bonds, while non-bonding electrons (lone pairs) are not.

Front

How does the presence of lone pairs affect molecular shape?

Back

Lone pairs repel more strongly than bonding pairs, altering the shape of the molecule.

Front

What is the molecular geometry of BF₃?

Back

Trigonal planar.
