Vedclass · Answer

(A) In a diatomic molecule,the $2s$ atomic orbitals combine to form one bonding molecular orbital $(\sigma 2s)$ and one antibonding molecular orbital $(\sigma^* 2s)$.The $2p$ atomic orbitals combine to form three bonding molecular orbitals $(\sigma 2p_z, \pi 2p_x, \pi 2p_y)$ and three antibonding molecular orbitals $(\sigma^* 2p_z, \pi^* 2p_x, \pi^* 2p_y)$.Total number of antibonding molecular orbitals $= 1 (	ext{from } 2s) + 3 (	ext{from } 2p) = 4$.

The total number of antibonding molecular orbitals,formed from $2s$ and $2p$ atomic orbitals in a diatomic molecule is . . . . . .
