Covalent and VSEPR Theory

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed when 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 difference between electronic geometry and molecular geometry?

Back

Electronic geometry considers all electron pairs (bonding and lone pairs) around the central atom, while molecular geometry considers only the bonding pairs.

Front

What is the electronic 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 chemical formula for a compound formed between phosphorus and chlorine?

Back

PCl₅ (Phosphorus Pentachloride).

Front

What is the name of the compound with the formula TiF₃?

Back

Titanium (III) Fluoride.

Front

How do you determine the molecular geometry of a molecule?

Back

By using VSEPR theory to analyze the number of bonding and lone pairs around the central atom.

Front

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

Back

Bent.

Front

What is the significance of lone pairs in determining molecular geometry?

Back

Lone pairs occupy space and repel bonding pairs, affecting the overall shape of the molecule.
