Molecular Geometry Review

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 shape of a molecule?

Back

The shape of a molecule is determined by the arrangement of its atoms and the repulsion between electron pairs according to VSEPR theory.

Front

What is VSEPR theory?

Back

VSEPR (Valence Shell Electron Pair Repulsion) theory is a model used to predict the geometry of individual molecules based on the repulsion between electron pairs in the valence shell of the central atom.

What is a covalent bond?

Back

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

Front

What types of atoms typically form covalent bonds?

Back

Covalent bonds are typically formed between two nonmetals.

What is the molecular geometry of H2S?

Back

The molecular geometry of H2S (hydrogen sulfide) is bent due to the presence of lone pairs on the sulfur atom.

Front

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

Back

The shape of a molecule with four bonding pairs and no lone pairs is tetrahedral.

Front

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

Back

The shape of a molecule with three bonding pairs and one lone pair is trigonal pyramidal.

Front

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

Back

The shape of a molecule with two bonding pairs and two lone pairs is bent.

Front

What is the bond angle in a tetrahedral molecule?

Back

The bond angle in a tetrahedral molecule is approximately 109.5 degrees.
