Given below are two statements
Statement I : The N-N single bond is weaker and longer than that of $P - P$ 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

Question

TestHub · Accepted Answer

N ¨ − N ¨ single bond weaker than P ¨ − P ¨ due to more ℓ p − ℓ p repulsion. Bond length ⇒ d p − p ​ > d N − N ​ ( size ↑ , B.L. ↑ ) In group 15 elements only N \& P show disproportionation in +3 oxidation state, As, Sb \& Bi have almost inert for disproportionation in +3 oxidation state. So both statements are false.
