How many molecular orbitals are formed, when the 1s orbitals of two hydrogen atoms combine to form a hydrogen molecule?

Question

Quizplus · Accepted Answer

When the two 1s orbitals of hydrogen atoms combine, two molecular orbitals are formed: the bonding molecular orbital and the antibonding molecular orbital. The bonding molecular orbital results from constructive interference of the two 1s orbitals, while the antibonding molecular orbital results from destructive interference. The number of molecular orbitals formed is always equal to the number of atomic orbitals that combine. Therefore, in this case, the answer is 2 (choice B).
