VSEPR/MOLECULAR SHAPES REVIEW

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion.

Front

What is the primary focus of VSEPR theory?

Back

The central atom in a molecule.

Front

How do lone pairs affect molecular shape according to VSEPR theory?

Back

Lone pairs repel more strongly than bond pairs, affecting the overall shape.

Front

What is the molecular shape of a molecule with 4 bonding pairs and 0 lone pairs?

Back

Tetrahedral.

Front

What is the molecular shape of a molecule with 3 bonding pairs and 1 lone pair?

Back

Trigonal pyramidal.

Front

What is the molecular shape of a molecule with 2 bonding pairs and 2 lone pairs?

Back

Bent.

Front

How many total electron pairs are in a molecule with 3 bonding pairs and 2 lone pairs?

Back

5 total electron pairs.

Front

What is the effect of electronegativity on molecular shape?

Back

Electronegativity can influence the distribution of electron density, affecting bond angles.
