Answer 1

Answer on Question # 60479 - Chemistry - Organic Chemistry

What rule is violated in the following electronic configuration 1s¹ 1s² 2px² 2py¹ 2pz⁰.

Solution

According to the Hund’s rule, every orbital in a subshell should be occupied with one electron before any other orbital from this subshell is doubly occupied. The electronic configuration given for p subshell represents two electrons in px orbital, whereas the pz orbital is empty. It is not in compliance with the Hund’s rule. The correct electronic configuration should be

1s¹ 1s² 2px¹ 2py¹ 2pz¹.
