NEET Chemistry (general) MCQ Question
Type: MCQ-fact-Easy-Class 12
Why does nitrogen not form pentahalides despite exhibiting a +5 oxidation state?
A
Nitrogen lacks d orbitals to expand its covalence beyond four.
B
Nitrogen has a high electronegativity which prevents bond formation.
C
Nitrogen is a gas and cannot form solid compounds.
D
Nitrogen has a low atomic size that restricts bond formation.
Correct Answer
Option A
Detailed Explanation
Nitrogen, with n = 2, has only s and p orbitals and does not have d orbitals, which prevents it from expanding its covalence beyond four, thus it does not form pentahalides.
