ChemistrySingle correct+4 / -1Question 59 of 75

Correct statements from the following are:

A. Nitrogen in oxidation states from +1 to +4 disproportionates in acid medium.

B. Nitrogen has the ability to 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:

B, C and D Only

C, D and E Only

A, C and E Only

A and E Only

Answer and worked solution

Official answer: D

Each statement.

A: Nitrogen in oxidation states +1 to +4 tends to disproportionate in acid solution. True.
B: Nitrogen forms $p\pi$ - $p\pi$ multiple bonds. It has no d orbitals, so it cannot form $d\pi$ - $p\pi$ bonds. False.
C: The N-N single bond is weaker than P-P, because lone pairs on the small N atoms repel. False.
D: Nitrogen, a gas, has the lowest density in the group. False.
E: Nitrogen has only four valence orbitals (2s, 2p), so its covalency is at most four. True.

Correct: A and E.

(D)
