Vedclass · Answer

(A) In the ethene molecule $(C_2H_4)$,the two carbon atoms are $sp^2$ hybridized. The $C-C$ $\sigma$-bond and the four $C-H$ $\sigma$-bonds lie in the same plane,known as the molecular plane. The $\pi$-bond is formed by the lateral overlap of the unhybridized $2p_z$ orbitals of the carbon atoms,which are perpendicular to the molecular plane. $A$ nodal plane is a plane where the probability of finding an electron is zero. For the $\pi$-bond in ethene,the molecular plane itself acts as the nodal plane because the electron density of the $\pi$-bond is concentrated above and below this plane.

Which of the following represents the nodal plane in the $\pi$-bond of ethene $(C_2H_4)$?
