Which of the following is a condition for the combination of atomic orbitals?(a) Combining atomic orbitals need not have equal energy(b) Combining atomic orbitals must have symmetry as per molecular axis(c) Combining atomic orbitals must overlap to a minimum extent(d) For combining atomic orbitals, X-axis should be taken as a molecular axisI have been asked this question in unit test.I want to ask this question from Molecular Orbital Theory in division Chemical Bonding and Molecular Structure of Chemistry – Class 11

Answer»

Correct OPTION is (b) COMBINING ATOMIC orbitals must have symmetry as per molecular AXIS

To elaborate: Combining atomic orbitals must have symmetry as per molecular axis is TRUE. The corrected statements are combining atomic orbitals must have equal energy, must overlap to the maximum extent and Z-axis should be taken as the molecular axis.
