VSEPR

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion

Front

What is the primary purpose of VSEPR theory?

Back

To predict the molecular shape based on electron pair repulsion.

Front

What is a lone pair in the context of VSEPR theory?

Back

A pair of non-bonding electrons that can affect molecular geometry.

Front

How does a lone pair affect molecular shape compared to bonding pairs?

Back

Lone pairs occupy more space and can compress bond angles between bonding pairs.

Front

What molecular geometry is associated with four bonding pairs and no lone pairs?

Back

Tetrahedral.

Front

What molecular geometry is associated with three bonding pairs and one lone pair?

Back

Trigonal pyramidal.

Front

What molecular geometry is associated with two bonding pairs and two lone pairs?

Back

Bent.

Front

What is the molecular shape of CO2?

Back
