1 Comment / chemical bonding, chemistry

Molecular Orbital Diagram of O2 Molecular orbital (MO) theory explains the construction of a molecular orbital diagram on the basis of the following main points. Formation of MOs: Atomic orbitals(AOs) linearly combine with each other to form an equal number of molecular orbitals (MOs). 2. Energy of MOs: Half of the molecular orbitals (MOs) having …

Valence Bond (VB) Theory Notes

32 Comments / chemical bonding, chemistry

Valence Bond (VB) Theory: This theory has the following postulates: Covalent bonds are formed by overlapping atomic orbitals. Electron density is high in the overlapped area and is thus responsible for holding atoms together. Only half-filled atomic orbitals take part in covalent bond formation. The half-filled atomic orbitals must contain electrons with opposite so they …

Do you know !! What is resonance theory? Resonance Theory: According to resonance theory some molecules are represented by two or more than two structures and the actual structure is weighed average of these and is called resonance hybrid. There are certain molecules which cannot be represented by single structure, so we write various possible …
