Chem Molecular Geometry with VSEPR

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 the electron pairs in the valence shell of the central atom.

Front

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

Back

Tetrahedral.

Front

What is the bond angle in a trigonal planar molecule?

Back

120 degrees.

Front

What determines if a molecule is polar or non-polar?

Back

The shape of the molecule and the difference in electronegativity between the atoms.

Front

What is a covalent bond?

Back

A covalent bond is formed when two atoms share at least one pair of electrons.

Front

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

Back

Bent.

Front

What is the bond angle in a linear molecule?

Back

180 degrees.

Front

What is the shape of a molecule with five bonding pairs?

Back

Trigonal bipyramidal.

Front

What is the significance of lone pairs in molecular geometry?

Back

Lone pairs occupy space and can affect the bond angles and overall shape of the molecule.

Front

How does electronegativity affect molecular polarity?

Back

Differences in electronegativity between bonded atoms can create dipoles, leading to molecular polarity.
