Solution


Q.

The linear combination of atomic orbitals to form molecular orbitals takes place only when the combining atomic orbitals             
A. have the same energy
B. have the minimum overlap
C. have same symmetry about the molecular axis
D. have different symmetry about the molecular axis

Choose the most appropriate from the options given below:                     [2024]
1 A, B, C only  
2 A and C only  
3 B and D only  
4 B, C, D only  

Ans.

(2)

Atomic orbitals taking part in linear combination of atomic orbitals (LCAO) should have equal or nearly equal energy. Combining orbitals should have same symmetry about the molecular axis.
