Q.
Two pi and half sigma bonds are present in:
JEE MainJEE Main 2019Chemical Bonding and Molecular Structure
Solution:
$N _2^{\oplus} \Rightarrow BO =2 \cdot 5 \Rightarrow\left[\pi-\right.$ Bond-$2 \& \sigma-$ Bond $\left.=\frac{1}{2}\right]$
$N _2 \Rightarrow B \cdot O \cdot=3 \cdot 0 \Rightarrow[\pi-$ Bond $=2 \& \sigma-$ Bond $=1]$
$O _2^{\oplus}= B \cdot O \cdot \Rightarrow 2 \cdot 5 \Rightarrow[\pi-$ Bond $=1 \cdot 5 \& \sigma-$ Bond $=1]$
$O _2 \Rightarrow B \cdot O \cdot \Rightarrow 2 \Rightarrow[\pi-$ Bond $\Rightarrow 1 \& \sigma-$ Bond $=1]$
