VSEPR & Hybridization

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.

What does hybridization refer to in chemistry?

Back

Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals, which can then form bonds with other atoms.

Front

What is sp hybridization?

Back

sp hybridization occurs when one s orbital and one p orbital mix to form two equivalent sp hybrid orbitals, resulting in a linear geometry with a bond angle of 180°.

Front

What is sp² hybridization?

Back

sp² hybridization occurs when one s orbital and two p orbitals mix to form three equivalent sp² hybrid orbitals, resulting in a trigonal planar geometry with bond angles of 120°.

Front

What is sp³ hybridization?

Back

sp³ hybridization occurs when one s orbital and three p orbitals mix to form four equivalent sp³ hybrid orbitals, resulting in a tetrahedral geometry with bond angles of 109.5°.

Front

How many sigma bonds are in a double bond?

Back

A double bond consists of one sigma bond and one pi bond.

Front

How many pi bonds are in a triple bond?

Back

A triple bond consists of one sigma bond and two pi bonds.

Front

What is the shape of a molecule with sp hybridization?

Back

The shape of a molecule with sp hybridization is linear.

Front

What is the shape of a molecule with sp² hybridization?

Back

The shape of a molecule with sp² hybridization is trigonal planar.

Front

What is the shape of a molecule with sp³ hybridization?

Back

The shape of a molecule with sp³ hybridization is tetrahedral.
