The $p-p$ orbital overlapping is present in the following molecule:

How and when is a $\pi$-bond formed by the overlapping of orbitals?

The bond in the formation of fluorine molecule will be

Which of the following would result in the formation of the strongest $\pi-$ bond if the molecular axis is the $x-$axis?

Given below are two statements :
Statement $(I)$ : The oxidation state of an element in a particular compound is the charge acquired by its atom on the basis of electron gain enthalpy consideration from other atoms in the molecule.
Statement $(II)$ : $p\pi-p\pi$ bond formation is more prevalent in second period elements over other periods.
In the light of the above statements,choose the most appropriate answer from the options given below :

The angle between $p$-orbitals is ......
