NEETChemistryp Block Elements (Group 15, 16, 17 & 18)
What is the expected order of successive ionization enthalpies for Group 15 elements?
Options
- A∆iH1 < ∆iH2 < ∆iH3
- B∆iH1 > ∆iH2 > ∆iH3
- C∆iH1 = ∆iH2 = ∆iH3
- D∆iH1 ∆iH3
Correct answer
A. ∆iH1 < ∆iH2 < ∆iH3
Step-by-step solution
The paragraph states that the expected order of successive ionization enthalpies is ∆iH1 < ∆iH2 < ∆iH3.
