QNEET-2019-Ch-748: NEET 2019 Chemistry - Class 11 NEET-2019-Ch-748 Solution: 4d 5p 5f and 6p orbitals are arranged in the order of…
4d 5p 5f and 6p orbitals are arranged in the order of decreasing energy. The correct option is: 6p > 5f > 4d > 5p 5f > 6p > 4d > 5p 5f > 6p > 5p > 4d 6p > 5f > 5p > 4d
Multiple Choice Options
- A 6p > 5f > 4d > 5p
- B 5f > 6p > 4d > 5p
- C 5f > 6p > 5p > 4d
- D 6p > 5f > 5p > 4d
Step-by-Step Verified Solution
As per Aufbau principle (n + l rule), higher is
the value of (n + l), greater will be the energy. When (n + l) values are same then which orbital have higher value of n will have more energy.
4d = 4 + 2 = 6
5p = 5 + 1 = 6
5f = 5 + 3 = 8
6p = 6 + 1 = 7
Hence, the correct order of decreasing energy will
be : 5f > 6p > 5p > 4d.
