VSEPR

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion.

Front

What is the main purpose of VSEPR theory?

Back

To predict the molecular shape based on the repulsion between electron pairs.

Front

Front

What is the molecular shape of NH3 (ammonia)?

Back

Trigonal pyramidal.

Front

How does the presence of lone pairs affect molecular shape?

Back

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