Select the molecule which does not have a pie ($\mathrm{\pi }$) bond

The molecule which does not have a pie ($\mathrm{\pi }$) bond is ${\mathrm{NOF}}_3$

The sideways positive overlap of atomic orbitals in a direction perpendicular to the internuclear axis results in the formation of pi bonds. 

Atomic orbital axes are parallel to one another whereas overlapping is perpendicular to the internuclear axis during the creation of bonds.

${\mathrm{NOF}}_3$ structure does not follows the condition of forming the pi bond.

Hence, the molecule which does not have a pie ($\mathrm{\pi }$) bond is ${\mathrm{NOF}}_3$
