Which of the following statements is not true regarding molecular orbital theory? O Bonding molecular orbitals have lower energy
pychu [463]

Answer:

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.
