Both $a$ and $b$ are correct

Vedclass · Answer

(C) According to the Pauli Exclusion Principle and the valence bond theory,for a stable covalent bond to form,the electrons in the overlapping orbitals must have opposite spins. If the electrons have the same spin,the Pauli Exclusion Principle prevents them from occupying the same region of space with the same quantum numbers. Consequently,the orbitals do not overlap effectively,and no chemical bond is formed. Therefore,both statements $a$ and $b$ are correct.
