MCQ
Two pi and half sigma bonds are present in
  • A
    $O_2^ + $
  • B
    $N_2$
  • C
    $O_2$
  • $N_2^ + $

Answer

Correct option: D.
$N_2^ + $
d
${N_{{2^ \oplus }}} \Rightarrow BO = 2.5 \Rightarrow [\pi  = Bond = 2\,\& \sigma  - Bond = \frac{1}{2}]$

${N_2} \Rightarrow B.O. = 3.0 \Rightarrow [\pi  - Bond = 2\,\& \sigma  - Bond = 1]$

${O_{{2^ \oplus }}} = B.O. \Rightarrow 2.5 \Rightarrow [\pi  - Bond = 1.5\,\& \sigma  - Bond = 1]$

${O_2} \Rightarrow B.O. \Rightarrow 2 \Rightarrow [\pi  - Bond \Rightarrow 1\,\& \sigma  - Bond = 1]$
