Valence Bond Theory Hybridization Quiz

What is the hybridization of an atom in a molecule with four sigma bonds and no lone pairs?

• sp2

• sp

• sp3d

• sp3

Answer explanation

The hybridization of an atom in a molecule with four sigma bonds and no lone pairs is sp3. In sp3 hybridization, the atom forms four sigma bonds by mixing one s orbital and three p orbitals.

Which type of hybridization is found in molecules with a trigonal planar molecular geometry?

• dsp2

• sp2

• sp3

• sp

Answer explanation

Molecules with a trigonal planar molecular geometry exhibit sp2 hybridization, where one s orbital and two p orbitals combine to form three hybrid orbitals.

What is the hybridization of an atom in a molecule with two sigma bonds and two lone pairs?

• sp4

• sp3

• sp

• sp2

Answer explanation

The hybridization of an atom in a molecule with two sigma bonds and two lone pairs is sp3. In sp3 hybridization, an atom forms four sigma bonds by mixing one s orbital and three p orbitals.

Which type of hybridization is found in molecules with a linear molecular geometry?

• dsp3

• sp

• sp2

• sp3

Answer explanation

In molecules with a linear molecular geometry, the type of hybridization is sp. This hybridization allows for the formation of two sigma bonds and results in a linear shape.

What is the hybridization of an atom in a molecule with three sigma bonds and one lone pair?

• sp3

• sp

• sp2

• sp3d

Answer explanation

The hybridization of an atom in a molecule with three sigma bonds and one lone pair is sp3. This hybridization allows for the formation of four sigma bonds, satisfying the octet rule.

Which type of hybridization is found in molecules with a tetrahedral molecular geometry?

• sp3

• sp2

• sp

• dsp3

Answer explanation

Molecules with a tetrahedral molecular geometry exhibit sp3 hybridization, where one s orbital and three p orbitals combine to form four sp3 hybrid orbitals.

What is the hybridization of an atom in a molecule with one sigma bond and three lone pairs?

• sp

• sp4

• sp3

• sp2

Answer explanation

The hybridization of an atom in a molecule with one sigma bond and three lone pairs is sp3. In sp3 hybridization, one s orbital and three p orbitals combine to form four sp3 hybrid orbitals, allowing for the formation of four sigma bonds.

Which type of hybridization is found in molecules with a trigonal bipyramidal molecular geometry?

• sp2d

• sp3

• sp3d

• sp3d2

Answer explanation

In molecules with a trigonal bipyramidal molecular geometry, the hybridization is sp3d. This hybridization allows for the formation of five sigma bonds, resulting in a trigonal bipyramidal shape.

What type of bond is formed by the overlap of atomic orbitals along the internuclear axis?

• Hydrogen bond

• Ionic bond

• Van der Waals bond

• Covalent bond

Answer explanation

A covalent bond is formed by the overlap of atomic orbitals along the internuclear axis. It involves the sharing of electrons between atoms.

What type of bond is formed by the sideways overlap of atomic orbitals?

• ionic bond

• sigma bond

• covalent bond

• pi bond

Answer explanation

A pi bond is formed by the sideways overlap of atomic orbitals, making it the correct choice.
