Question

Identify the incorrect statements about group 15 elements:

(A) Dinitrogen is a diatomic gas which acts like an inert gas at room temperature.

(B) The common oxidation states of these elements are 3-3, +3+3 and +5+5.

(C) Nitrogen has unique ability to form pπpπ\mathrm{p\pi - p\pi} multiple bonds.

(D) The stability of +5 oxidation states increases down the group.

(E) Nitrogen shows a maximum covalency of 6.

Choose the correct answer from the options given below:

Options
  1. a

    (A), (C), (E) only

  2. b

    (B), (D), (E) only

  3. c

    (D) and (E) only

  4. d

    (A), (B), (D) only

Correct Answerc

(D) and (E) only

Detailed Solution

Strategy: Predict the geometry and properties of Xenon oxides/fluorides.

Step 1: Structure Determination Identify the central atom (\ceXe)(\ce{Xe}) and its valence electrons (8). Calculate bond pairs and lone pairs based on the given species.

Step 2: Conclusion Matching the geometry/hybridization (e.g., sp3sp^3 for \ceXeO3\ce{XeO3} or sp3d2sp^3d^2 for \ceXeF4\ce{XeF4}) yields the correct answer.
