Back

Trigonal pyramidal.

Front

What is the molecular geometry of HCN?

Back

Linear.

Front

What is the polarity of a linear molecule like HCN?

Back

Polar molecule.

Front

How many lone pairs of electrons are around the central atom in a molecule with 4 bonds?

Back

0 lone pairs of electrons.

Front

Why do bonds in molecules move as far apart from each other as possible?

Back

The electrons that make up the bonds repel each other.

Front

What is the shape of a molecule with 2 bonds and 2 lone pairs around the central atom?

Back

Bent.

Front

What is the shape of a molecule with 4 bonds and no lone pairs around the central atom?

Back

Tetrahedral.

Front

What is the term for the three-dimensional arrangement of atoms in a molecule?

Back

Molecular geometry.

Front

What is the effect of lone pairs on molecular shape?

Back

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

Front

What is the VSEPR theory?

Back

Valence Shell Electron Pair Repulsion theory; it predicts the shape of molecules based on electron pair repulsion.
