Question

Choose the incorrect statement from the following -

• A. In bonding molecular orbital, electron density is low in the region between the nuclei of bonded atoms.
• B. The energy of antibonding molecular orbital is higher than that of atomic orbitals from it is formed.
• C. Every electron in bonding molecular orbital contribute towards the stability of molecules.
• D. Antibonding takes place when lobes of atomic orbitals have different signs.

Answer 1

The correct option is A In bonding molecular orbital, electron density is low in the region between the nuclei of bonded atoms.

In bonding molecular orbital, electron density is high in the region between the nuclei of bonded atoms, all other options are correct. The energy of antibonding molecular orbital is higher than that of atomic orbitals from it is formed. Every electron in bonding molecular orbital contribute towards the stability of molecules. Antibonding takes place when lobes of atomic orbitals have different signs.
