Covalent and VSEPR Theory

Front

What is the definition of covalent bonding?

Back

Covalent bonding is a type of chemical bond where two atoms share one or more pairs of electrons.

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.

Front

What is the electronic geometry of a molecule?

Back

Electronic geometry refers to the spatial arrangement of all electron pairs (bonding and lone pairs) around the central atom.

Front

What is the molecular geometry of a molecule?

Back

Molecular geometry describes the three-dimensional arrangement of the atoms in a molecule, considering only the bonding pairs of electrons.

Front

What is the difference between electronic geometry and molecular geometry?

Back

Electronic geometry includes all electron pairs (bonding and lone pairs), while molecular geometry only considers the arrangement of atoms (bonding pairs).

Front

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

Back

Tetrahedral.

Front

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

Back

Trigonal pyramidal.

Front

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

Back

Bent.

Front

What is the chemical formula for a molecule with one phosphorus atom and five chlorine atoms?

Back

PCl₅.

Front

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

Back

Linear.
