A bonding molecular orbital is formed when the electron waves of the combining atoms are in phase.

Text Solution

AI Generated Solution

### Step-by-Step Solution: 1. **Understanding Bonding Molecular Orbitals**: - A bonding molecular orbital is formed when the atomic orbitals of two atoms combine in such a way that their electron waves are in phase. This means that the peaks of the wave functions align with each other. 2. **In-Phase Combination**: - The in-phase combination refers to the constructive interference of the wave functions. When two atomic orbitals combine in phase, they add together to form a new orbital that is lower in energy than the individual atomic orbitals. ...

How many molecular orbitals are formed by the combination of two lithium atoms?

According to MOT, two atomic orbitals overlap resulting in the formation of molecular orbital formed. Number of atomic orbitals overlapping together is equal to the molecule orbital formed. The two atomic orbital thus formed by LCAO (linear combination of atomic orbital) in the phase or in the different phase are known as bonding and antibonding molecular orbitals respectively. The energy of bonding molecular orbital is lower than that of the pure atomic orbitals by an amount Delta . This known as the stabilization energy. The enerby of antibonding molecular orbital in increased by Delta' (destabilisation energy). Q. How many nodal plane is present in sigma_(s and p) bonding molecular orbital ?
