• A. $\sigma -$ bond lies on the line joining the nuclei of bonded atoms
• B. $\pi -$ electron cloud lies on either side to the line joining the nuclei of bonded atoms
• C. $(2p_{\pi }-3d_{\pi })$ pi-bond is stronger than $(2p_{\pi }-3d_{\pi })$ pi-bond.
• D. $\sigma -$bond has primary effect of decide direction of covalent bond, while $\pi -$bond has no primary effect in direction of bond
