Covalent Bonds - Molecular Geometry

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 molecular geometry?

Back

Molecular geometry refers to the three-dimensional arrangement of atoms within a molecule.

Front

Define tetrahedral molecular geometry.

Back

Tetrahedral molecular geometry occurs when a central atom is bonded to four other atoms, forming a shape like a pyramid with a triangular base.

Front

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

Back

Linear.

Front

What is the shape of a molecule with three bonded atoms and one lone pair?

Back

Trigonal pyramidal.

Front

What is the shape of a molecule with two bonded atoms and one lone pair?

Back

Bent.

Front

What is the VSEPR theory?

Back

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 molecular geometry of water (H2O)?

Back

Bent.

Front

What is the molecular formula for Diphosphorous pentoxide?

Back

P2O5.

Front

How does the presence of lone pairs affect molecular geometry?

Back

Lone pairs repel more strongly than bonding pairs, which can alter the shape of the molecule.
