QNEET-2022-Ch-494: NEET 2022 Chemistry - Class 11 NEET-2022-Ch-494 Solution: The correct order of first ionization enthalpy for the given…
The correct order of first ionization enthalpy for the given four elements is: C < F < N < O C < N < F < O C < N < O < F C < O < N < F
Multiple Choice Options
- A C < F < N < O
- B C < N < F < O
- C C < N < O < F
- D C < O < N < F
Step-by-Step Verified Solution
_ Generally, on moving left to right in a period. First ionization enthalpy of elements increases due to increase in effective nuclear charge.
_ Due to more stable half-filled outer electronic configuration (2s 2 2p 3 ) of N, its first ionization enthalpy is more than O.
So, correct order of IP is : C < O < N < F
