When a molecular orbital is formed by combining atomic orbitals, the probability of finding an electron in the nodal plane is

1. minimum in the nodal plane
2. maximum in the nodal plane
3. zero in the nodal plane
4. zero on the surface of the lobe

Correct answer: zero in the nodal plane

Solution

A nodal plane is by definition a surface where the probability of finding an electron is exactly zero.
