According to the molecular orbital theory:
A) molecular orbitals are products of vawefunctions describing the atomic orbitals; two atomic orbitals produce only one molecular orbital
B) bonding molecular orbitals are lower in energy than the atomic orbitals they were formed from, while antibonding molecular orbitals have greater energy than the original atomic orbitals.
C) Sigma molecular orbitals are always centrosymmetric and cannot have any nodes.

Question

Quizplus · Accepted Answer

Molecular orbital theory posits that when atomic orbitals combine, they form molecular orbitals where electrons are delocalized over the entire molecule. Bonding molecular orbitals result from constructive interference of atomic orbitals, leading to lower energy than the original atomic orbitals. Conversely, antibonding molecular orbitals are formed from destructive interference, resulting in higher energy than the atomic orbitals they originate from.
