Identify the incorrect statement from the following:

Solution & Explanation

Related Formula
Nitrogen electronic configuration: 1s² 2s² 2p³ (No vacant d-orbitals)
Core Logic

Nitrogen lacks vacant d-orbitals in its valence shell (n=2). Therefore, it cannot form dπ-pπ or dπ-dπ bonds. Statement (2) is incorrect.

Step 1: Conclusion

Incorrect statement is (2).

Pattern Recognition

Second period elements (N, O, F) cannot form dπ bonds due to non-availability of d orbitals.

Q62 neet_2024_05_may_morning Properties of Group 14 and 16 Elements
Identify the incorrect statement from the following:
  • A. (1) Carbon has the ability to form pπ-pπ multiple bond with itself.
  • B. (2) ECl₃ (E = B and Al) is a monomer when E = B and a dimer when E = Al.
  • C. (3) Oxygen exhibits only -2 oxidation state.
  • D. (4) The order of catenation property of Group 14 elements is C gg Si > Ge ≈ Sn.

Solution

Related Formula
Oxidation states of Oxygen: O₂ (0), OF₂ (+2), O₂F₂ (+1), H₂O₂ (-1), H₂O (-2)
Core Logic

Statement (3) is incorrect because oxygen exhibits oxidation states of 0 in O₂, +2 in OF₂, +1 in O₂F₂, and -1 in peroxides.

Step 1: Conclusion

Incorrect statement is (3).

Pattern Recognition

Oxygen shows positive oxidation states with fluoride (OF₂, O₂F₂) and -1 state in peroxides.
