What is the expected order of ionization enthalpies for group 13 elements?
Options
- A∆iH1<∆iH2<∆iH3
- B∆iH1>∆iH2>∆iH3
- C∆iH1=∆iH2=∆iH3
- D∆iH1 and ∆iH2 are equal, but ∆iH3 is different
Correct answer
A. ∆iH1<∆iH2<∆iH3
Step-by-step solution
The expected order of ionization enthalpies is ∆iH1<∆iH2<∆iH3.
