During the formation of a molecular orbital from atomic orbitals, probability of electron density is
less in the nodal plane
maximum in the nodal plane
zero in the nodal plane
zero on the surface of the lobe
The pairs of species of oxygen and their magnetic behaviour are noted below. Which of the following presents the correct description ?
Consider the species $CH _{4}, NH _{4}^{+}$and $BH _{4}^{-}$. Choose the correct option with respect to the there species .... .
Paramagnetism is exhibited by molecules
Match $List-I$ with $List-II$.
$List-I$ | $List-II$ |
$(A)$ $\Psi_{ MO }=\Psi_{ A }-\Psi_{ B }$ | $(I)$ Dipole moment |
$(B)$ $\mu=Q \times I$ | $(II)$ Bonding molecular orbital |
$(C)$ $\frac{N_{b}-N_{a}}{2}$ | $(III)$ Anti-bonding molecualr orbital |
$(D)$ $\Psi_{ MO }=\Psi_{ A }+\Psi_{ B }$ | $(IV)$ Bond order |
Bond order normally gives idea of stability of a molecular species. All the molecules viz. $H_2,\,\, Li_2$ and $B_2$ have the same bond order yet they are not equally stable. Their stability order is
