  1. A \(He _{2}^{+}\)
  2. B \(He _{2}^{-}\)
  3. C \(Be _{2}\)
  4. D \(O _{2}^{2-}\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(Be _{2}\)

Step-by-step Solution

Detailed explanation

Chemical Species Bond Order \(He _{2}^{+}\) \(0.5\) \(He _{2}^{-}\) \(0.5\) \(Be _{2}\) \(0\) \(O _{2}^{2-}\) \(1\) According to \(M.O.T.\) If bond order of chemical species is zero then that chemical species does not exist.
