Understanding Hybridization

Why do central atoms like carbon tend to hybridize?

• They have more electrons.

• They form multiple bonds.

• They are larger in size.

• They are more electronegative.

Which of the following atoms is least likely to hybridize?

• Oxygen

• Hydrogen

• Carbon

• Nitrogen

What is the main reason terminal atoms do not hybridize?

• They are too small.

• They form only one bond.

• They have too many electrons.

• They are too electronegative.

What is the percentage of s character in sp3 hybridization?

• 50%

• 100%

• 25%

• 75%

How does the bond angle in sp3 hybridization compare to VSEPR theory?

• It is larger in sp3 hybridization.

• It is smaller in sp3 hybridization.

• It is the same in both models.

• It is not comparable.

What is the main difference between sp3 hybridization and VSEPR theory?

• VSEPR theory focuses on bond angles.

• VSEPR theory is based on mathematical combinations.

• sp3 hybridization focuses on orbital overlap.

• sp3 hybridization is based on electron repulsion.

What is the bond angle in methane according to sp3 hybridization?

• 109.5 degrees

• 120 degrees

• p orbitals of hydrogen

• s orbitals of hydrogen

How does the presence of a lone pair affect the bond angle in ammonia?

• It has no effect on the bond angle.

• It increases the bond angle.

• It decreases the bond angle.

• It makes the bond angle exactly 109.5 degrees.

What is the bond angle in ammonia due to the lone pair?

• 107 degrees

• 109.5 degrees

• 90 degrees

• 120 degrees
