What is Molecular Geometry?

Back

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

Front

What are electron groups in molecular geometry?

Back

Electron groups include both bond groups (bonds between atoms) and lone pairs (non-bonding electrons) around a central atom.

Front

How many electron groups does a central atom with 3 bonds and no lone pairs have?

Back

3 electron groups.

Front

What is the molecular shape of a molecule with 4 electron groups and no lone pairs?

Back

Tetrahedral.

Front

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

Back

Trigonal Pyramidal.

Front

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

Back

Bent.

Front

How do lone pairs affect molecular geometry?

Back

Lone pairs occupy space and can repel bonding pairs, altering the shape of the molecule.

Front

What is the bond angle in a tetrahedral molecular geometry?

Back

Approximately 109.5 degrees.

Front

What is the bond angle in a trigonal planar molecular geometry?

Back

Approximately 120 degrees.

Front

What is the bond angle in a linear molecular geometry?

Back

180 degrees.
