Correct statements from the following are: Choose the correct answer from the options given below:

  1. B, C and D Only
  2. C, D and E Only
  3. A, C and E Only
  4. A and E Only

Answer

(4) A and E Only

Solution

A. Correct – as per NCERT, nitrogen in oxidation states +1 to +4 tends to disproportionate in acid solution (e.g. 3HNO2 HNO3 + H2O + 2NO).

B. Incorrect – nitrogen forms pπ–pπ multiple bonds with itself and with C and O; it has no d orbitals, so it cannot form dπ–pπ bonds.

C. Incorrect – because of the small bond length, the non-bonding electron pairs repel strongly, so the N–N single bond is weaker than the P–P single bond.

D. Incorrect – density increases down group 15; nitrogen has the lowest density.

E. Correct – nitrogen has only four valence orbitals (one 2s and three 2p), so its maximum covalency is four.

∴ Correct statements: A and E

Answer: (4)
