Which of the following statement is wrong?

Options

  1. ANitrogen cannot form d -p bond.
  2. BSingle N - N bond is weaker than the single P - P bond,
  3. CN ₂ O ₄ has two resonance structures
  4. DThe stability of hydrides increases from NH ₃ to BiH ₃ in group 15 of the periodic table

Correct answer

D. The stability of hydrides increases from NH ₃ to BiH ₃ in group 15 of the periodic table

Step-by-step solution

Stability of hydrides decreases down the group from NH ₃ to BiH ₃ as M - H bond energy decreases.
