Which of the following statements is/are not correct for combination of atomic orbitals?
(i) The combining atomic orbitals must have the same or nearly the same energy.
(ii) Greater the extent of overlap, the greater will be the electron density between the nuclei of a moleculer orbital.
(iii) 
orbital of one atom can combine with either of 
or 
orbital of other atom as these orbitals have same energy.
(iv) Overlapping in case of 
-bond takes place to a larger extent as compared to 
-bond.
Text Solution
Verified by ExpertsB
Atomic orbitals having same or nearly same energy will not combine if they do not have the same symmetry. 
orbital of one atom cannot combine with 
or 
orbital of other atom because of their different symmetries.
