Covalent Bonding and VSEPR

Front

What is covalent bonding?

Back

Covalent bonding is a type of chemical bond where two atoms share one or more pairs of electrons to achieve stability.

Front

What is hybridization in chemistry?

Back

Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals that can form covalent bonds.

What is the hybridization of a linear molecule?

Front

What is a sigma bond?

Back

A sigma bond is a type of covalent bond formed by the direct overlap of atomic orbitals, allowing for free rotation.

Front

What is a pi bond?

Back

A pi bond is a type of covalent bond formed by the side-to-side overlap of p orbitals, which restricts rotation.

Front

How many sigma and pi bonds are in a molecule with 5 sigma and 0 pi bonds?

Back

5 sigma and 0 pi bonds.

Front

What are London dispersion forces?

Back

London dispersion forces are weak intermolecular forces arising from temporary dipoles in molecules.

Front

What is a hydrogen bond?

Back

A hydrogen bond is a strong type of dipole-dipole attraction that occurs between a hydrogen atom bonded to a highly electronegative atom and another electronegative atom.

Front

Rank these in order of strength: London dispersion forces, hydrogen bond, dipole-dipole attraction.

Back

Hydrogen bond > dipole-dipole > London dispersion forces.

Front

What is VSEPR theory?

Back

VSEPR (Valence Shell Electron Pair Repulsion) theory is a model used to predict the geometry of molecules based on the repulsion between electron pairs.
