NEET2023ChemistryChemical Bonding and Molecular StructureActual
Which one of the following statements is incorrect related to Molecular Orbital Theory?
Options
- AMolecular orbitals obtained from 2 p _ x and 2 p _ y orbitals are symmetrical around the bond axis.
- BA -bonding molecular orbital has larger electron density above and below the internuclear axis.
- CThe ^* antibonding molecular orbital has a node between the nuclei.
- DIn the formation of bonding molecular orbital, the two electron waves of the bonding atoms reinforce each othe
Correct answer
A. Molecular orbitals obtained from 2 p _ x and 2 p _ y orbitals are symmetrical around the bond axis.
Step-by-step solution
- According to molecular orbital theory, the sigma ( ) molecular orbitals are symmetrical around the bond-axis while pi ( ) molecular orbitals are not symmetrical. As z -axis is taken as internuclear axis, 2 p_x and 2 p_y forms molecular orbitals, hence these are unsymmetrical around the bond-axis
