VSEPR

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion.

Front

What is the primary purpose of VSEPR theory?

Back

To determine the shape and geometry of molecules based on the repulsion between electron pairs.

Front

What VSEPR structure does NH3 (Ammonia) form?

Back

Triangular Pyramidal.

Front

What VSEPR structure does CO2 (Carbon Dioxide) form?

Back

Linear.

Front

What is the VSEPR structure of BCl3 (Boron Trichloride)?

Back

Trigonal Planar.

Front

How does VSEPR theory explain molecular shapes?

Back

It states that electron pairs around a central atom will arrange themselves to minimize repulsion.

Front

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

Back

A pair of valence electrons that are not shared with another atom.

Front

What is the effect of lone pairs on molecular geometry?

Back

Lone pairs take up more space than bonding pairs, affecting the overall shape.

Front

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

Back

Tetrahedral.

Front

What is the molecular shape of a molecule with two bonding pairs and two lone pairs?

Back

Bent.
