When three atomic orbitals of a central atom mix during hybridization, how many hybrid orbitals are formed?

• A. Three
• B. Four
• C. Two
• D. One

Answer: (A)

Verified step by step guidance

1. Understand that hybridization involves the mixing of atomic orbitals on the same atom to form new hybrid orbitals that are equivalent in energy and shape.
2. Recall that the number of hybrid orbitals formed is always equal to the number of atomic orbitals mixed during the hybridization process.
3. Given that three atomic orbitals are mixing, apply the rule that the number of hybrid orbitals formed equals the number of atomic orbitals combined.
4. Therefore, when three atomic orbitals mix, the number of hybrid orbitals formed is three.
5. This concept is fundamental in explaining molecular shapes and bonding properties in molecules.
