VSEPR/MOLECULAR SHAPES REVIEW

Front

What is the focus of VSEPR theory in a molecule?

Back

The central atom.

Front

Define a lone pair in the context of VSEPR theory.

Back

A pair of non-bonding electrons.

Front

What molecular shape does NH₄⁺ have?

Back

Tetrahedral.

Front

True or False: Electron pairs tend to be as far away as possible from each other to minimize repulsive interactions.

Back

True.

Front

Which molecule is represented by the formula CH₄?

Back

Methane.

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion.

Front

What is the molecular shape of CO₂?

Back

Linear.

Front

How do lone pairs affect molecular geometry?

Back

They occupy space and can repel bonding pairs, altering the shape.

Front

What is the molecular shape of PCl₅?

Back

Trigonal bipyramidal.

Front

What is the effect of electronegativity on molecular shape?

Back

More electronegative atoms can pull electron density, affecting bond angles.
