23-24 Molecular Geometry Honors Chem

Front

What is molecular geometry?

Back

Molecular geometry refers to the three-dimensional arrangement of atoms within a molecule, which affects its physical and chemical properties.

Front

What determines the polarity of a molecule?

Back

The polarity of a molecule is determined by the difference in electronegativity between the atoms and the shape of the molecule.

Front

What is a polar molecule?

Back

A polar molecule has a net dipole moment due to the presence of polar bonds and an asymmetrical shape.

Front

What is a nonpolar molecule?

Back

A nonpolar molecule has no net dipole moment, often due to symmetrical shape or equal sharing of electrons.

Front

Define covalent bond.

Back

A covalent bond is a chemical bond formed when two atoms share one or more pairs of electrons.

Front

What is the VSEPR theory?

Back

The Valence Shell Electron Pair Repulsion (VSEPR) theory predicts the shape of molecules based on the repulsion between electron pairs around a central atom.

Front

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

Back

The shape is tetrahedral.

Front

What is the shape of a molecule with three bonding pairs and one lone pair?

Back

The shape is trigonal pyramidal.

Front

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

Back

The shape is bent.

Front

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

Back

The shape is linear.
