Which one of the following compounds is not known?
Correct answer: D. NCl5
- A. SbCl3
- B. NCl3
- C. NI3
- D. NCl5
Explanation
NCl5 does not exist because there are no d-orbitals in the second energy level. Therefore there is no way to arrange five pairs of bonding electrons around a nitrogen atom.
