Kelly Gilbert · Answer 1

Option c, Two atomic orbitals combine to form one molecular orbital

Explanation:

Molecular orbitals are formed by linear combination of atomic orbitals.

Some of the important facts of molecular orbital theories are as follows:

No. of the molecular orbitals formed are equal to the no. of atomic orbitals participated. Half of the molecular orbitals are bonding molecular orbitals and half of the molecular orbitals are anti bonding molecular orbitals. Anti bonding molecular orbitals have energy higher than participating atomic orbitals. Bonding molecular orbitals have energy lower than participating atomic orbitals. Molecular orbitals are that region in the molecule where electrons are most likely to found.

So, among given, option c which is 'atomic orbitals combine to form one molecular orbital' is incorrect.
