Each orbital will take up a maximum of two electrons, each with its own amount of spin. Question 2: What is Nodal Plane? Answer: WebThe symmetry (parity) determines whether two orbitals can combine to form a bonding orbital or anti-bonding one, e.g. $\sigma$ or $\sigma ^*$ or $\pi$ or $\pi ^*$. Anti-bonding orbitals always have nodes. Nodal planes are also important in Diels Alder addition and similar reactions as here symmetry is important. phil hails-smith
