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 that can accommodate the bonding and lone pairs of electrons in a molecule.

Front

What is the molecular geometry of a molecule with sp³ hybridization and one lone pair?

Back

The molecular geometry is trigonal pyramidal.

Front

How many total electron pairs are in a molecule with sp³ hybridization?

Back

There are four total electron pairs (bonding and lone pairs) in a molecule with sp³ hybridization.

Front

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

Back

The shape is bent.

Front

What type of hybridization is present in a molecule with a linear geometry?

Back

The hybridization is sp.

Front

Which molecular geometry corresponds to sp² hybridization?

Back

The molecular geometry is trigonal planar.

Front

What is the effect of lone pairs on molecular geometry?

Back

Lone pairs repel more strongly than bonding pairs, which can alter the expected geometry of a molecule.

Front

What is the molecular geometry of CH₄?

Back

The molecular geometry of CH₄ is tetrahedral.

Front

How does the presence of multiple bonds affect hybridization?

Back

Multiple bonds (double or triple) typically involve the use of unhybridized p orbitals, affecting the overall hybridization of the molecule.
