Question:
$PCl_5$ is possible but $NCl_5$ does not exist :
$PCl_5$ is possible but $NCl_5$ does not exist :
Updated On: Jul 6, 2022
- in N, d-sub-shell is absent
- ionization energy of N is very high
- it does not like Cl
- None of these
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
$NCl_5$ in not possible because N does not contain d orbitals. Only nitrogen has a tendency to form $P \pi - P \pi$ multiple bonds. Other forms $d \pi - p \pi$ multiple bonds easily.

Group 15 Elements
Group 15 elements are also known as nitrogen group elements or nitrogen family.
It consists of:
- Nitrogen (N)
- Phosphorus (P)
- Arsenic (As)
- Antimony (Sb)
- Bismuth (Bi)
- Moscovium (Mc)
They are present on the right side of the periodic table. All the elements are arranged based on their atomic weight. The elements with similar properties reside in a column called the group.
All Group 15 elements have the electron configuration ns2np3 in their outer shell, where n is the principal quantum number.
