# The nodal plane in the $\pi$-bond of ethene is located in

$\begin{array}{1 1}(a)\;\text{a plane parallel to the molecular plane}\\(b)\;\text{a plane perpendicular to the molecular plane which bisects the carbon-carbon }\sigma-\text{bonded at right angle}\\(c)\;\text{the molecular plane}\\(d)\;\text{all of the above}\end{array}$

In ethene , pi-bond is perpendicular to the sigma bond formed between 2 carbons of ethene.
So, it is in the plane perpendicular to sigma bond.
The nodal plane means which does not contain in the pi- electrons.
So, the nodal plane of pi- bond will be along the molecular axis.
