JEE Main 2015 Chemistry question
After understanding the assertion and reason, choose the correct option. **Assertion:** In the bonding molecular orbital (MO) of , electron density is increased between the nuclei. **Reason:** The bonding MO is , which shows destructive interference of the combining electron waves.
Answer: (4)
Solution
The assertion is true: in the bonding molecular orbital of the electron density is indeed enhanced in the internuclear region, which is what screens the two nuclei from each other and holds the molecule together. The reason is partly right and partly wrong. It correctly identifies the bonding MO as the
