JEE Mains · Chemistry · STD 11 - 4. Chemical bonding and molecular structure
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:
- A \(A, B, C\) only
- B \(A\) and \(C\) only
- C \(B, C, D\) only
- D \(B\) and \(D\) only
Answer & Solution
