JEE Mains · Chemistry · STD 12 - p -Block elements - ll
Given below are two statements
Statement I : The N-N single bond is weaker and longer than that of \(\mathrm{P}-\mathrm{P}\) single bond
Statement II : Compounds of group 15 elements in +3 oxidation states readily undergo disproportionation reactions.
In the light of above statements, choose the correct answer from the options given below
- A Statement I is true but statement II is false
- B Both statement I and statement II are false
- C Statement I is false but statement II is true
- D Both statement I and statement II are true
Answer & Solution
Correct Answer
(B) Both statement I and statement II are false
Step-by-step Solution
Detailed explanation
\(\ddot{\mathrm{N}}-\ddot{\mathrm{N}}\) single bond weaker than \(\ddot{\mathrm{P}}-\ddot{\mathrm{P}}\) due to more \(\ell \mathrm{p}-\ell \mathrm{p}\) repulsion. Bond length \(\Rightarrow d_{p-p} \gt d_{N-N}(\operatorname{size} \uparrow\), B.L. \(\uparrow)\) In group 15…
