Last updated: 8/5/2022

To explain the covalent bond formation, valence bond theory is well known. Which of the following statement(s) is/are true? The covalent bond is formed due to the overlapping of two orbitals containing two unpaired electrons with the opposite spins The 'p' orbitals forming T-bond should have same sign with orientation in space Valence bond theory was not able to explain the paramagnetic nature of O2 It is possible that a covalent bond can be formed by the overlap of an electron filled orbital with vacant orbital
