Question
Correct statements from the following are:
A. Nitrogen in oxidation states from +1 to + 4 disproportionate in acid medium.
B. Nitrogen has the ability of form dπ-pπ multiple bonds with itself and other elements with small size and high electronegativity.
C. N-N single bond is stronger than P-P single bond.
D. Nitrogen has highest density in its group due to small size.
E. The maximum covalency of nitrogen is four since it has only four valence orbitals for bonding.
Choose the correct answer from the options given below:
Options
Solution
Sol. A) In the case of nitrogen, all oxidation states from + 1 to +4 tend to disproportionate in acid solution. For example. 3HNO₂ → HNO₃ + H₂O + 2NO
B) Nitrogen form pπ − pπ bonds with itself and other elements with small size and high electronegativity, dπ − pπ is not possible with itself as it has no d-orbital.
C) The single N-N bond is weaker than the single P-P bond because of high intereelecronic repulsion of the non-bonding electrons (lone pair), owing to the small bond length.
D) Nitrogen has lowest density in its group.
E) The maximum covalency of nitrogen is four.
Correct answer are (A) and (E)
