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
${N_{{2^ \oplus }}} \Rightarrow BO = 2.5 \Rightarrow [\pi = Bond = 2\,\& \sigma - Bond = \frac{1}{2}]$
${N_{{2^ \oplus }}} \Rightarrow BO = 2.5 \Rightarrow [\pi = Bond = 2\,\& \sigma - Bond = \frac{1}{2}]$
${N_2} \Rightarrow B.O. = 3.0 \Rightarrow [\pi - Bond = 2\,\& \sigma - Bond = 1]$
${O_{{2^ \oplus }}} = B.O. \Rightarrow 2.5 \Rightarrow [\pi - Bond = 1.5\,\& \sigma - Bond = 1]$
${O_2} \Rightarrow B.O. \Rightarrow 2 \Rightarrow [\pi - Bond \Rightarrow 1\,\& \sigma - Bond = 1]$
