Question
Which of the following statement is wrong?
-
The stability of hydrides increases from NH3 to BiH3 in group 15 of the periodic table.
-
Nitrogen cannot form dπ-pπ bond.
-
Single N - N bond is weaker than the single P - P bond.
-
N2O4 has two resonance structure
Solution
A.
The stability of hydrides increases from NH3 to BiH3 in group 15 of the periodic table.
The stability of hydrides decreases from NH3 to BiH3 which can be observed from their bond dissociation enthalpy. The correct order is NH3 < PH3 < AsH3 < SbH3 < BiH3
