Question

Which of the following linear combination of atomic orbitals will lead to formation of molecular orbitals in homonuclear diatomic molecules [internuclear axis in z-direction]? A. 2pz and 2px B. 2s and 2px C. 3dxy and 2 y x d D. 2s and 2pz E. 2pz and 2 y x d Choose the correct answer from the options given below:

(A) E only
(B) D only
(C) C and D only
(D) A and B only

Correct answer: B. For LCAO, orbitals combining should have proper symmetry. Eg. px with px, not with py or pz. Permitted symmetry is except those undergoing zero overlapping in VBT.
