Which of the following statement is correct?

Options

A. The bond length in CO is 1.128 Å and `CO^(+)` is 1.115Å because during conversion of CO to `CO^(+)`, electron is removed from anti bonding orbital
B. The bond length in CO is 1.115 Å and `CO^(+)` is 1.128Å because during conversion of CO to `CO^(+)`, electron is removed from anti bonding orbital
C. During conversion of `CO` to `CO^(+)` bond length does not vary because bond order remain same
D. The bond length in CO is 1.115 Å and `CO^(+)` is 1.128Å because bond order decreases during conversion of CO to `CO^(+)`

Answer

A
