4. The nodal plane in the $\pi$-bond of ethene is located in the plane of the molecule
(a) the molecular plane
(b) a plane parallel to the molecular plane
(c) a plane perpendicular to the molecular plane which bisects the carbon-carbon $\sigma$ bond at right angle
(d) a plane perpendicular to the molecular plane which contains the carbon-carbon $\sigma$ -bond

Answer:
Correct Answer: 4. (a)
Solution:
- Pi bond is formed by the $p$ -orbitals whose lobes have minima in the plane of molecule, hence molecular plane is the nodal plane of pi-bond.
