Multiple choice Identify the wrong statement. In group-15 of the periodic table, stability of hydrides increases from nitrogen hydride to bismuth hydride. d $\pi$ - p$\pi$ bond is not formed by nitrogen. Single P-P bond is stronger than single N-N bond. Two resonance structure is formed by N2O4. None of these Reveal answer Fill a bubble to check yourself A Correct answer Explanation Thermal stability of hydrides decreases as we go down the group. Hence, this option is correct.
