Which of the following statements is correct?

Options

  1. AThe bond length in C O is 1.128 Å and C O + is 1.115 Å because during conversion of C O to C O + , electron is
  2. BThe bond length in C O is 1.115 Å and C O + is 1.128 Å because during conversion of C O to C O + electron is r
  3. CDuring conversion of C O to C O + bond length does not vary because bond order remain same
  4. DThe bond length in C O is 1.115 Å and C O + is 1.128 Å because bond order decreases during conversion of C O t

Correct answer

A. The bond length in C O is 1.128 Å and C O + is 1.115 Å because during conversion of C O to C O + , electron is

Step-by-step solution

Because of the greater difference in electronegativity between C and O , the energy of the molecular orbitals in C O are in the following order σ 1 s 2 σ 1 s * 2 σ 2 s 2 π 2 p y 2 = π 2 p z 2 σ 2 p z 2 σ 2 s * 2 Bond order in C O = 1 2 10 – 4 = 3
