JEE Main 2025 (3 Apr Shift 1)
Question
Given below are two statements
Statement I : The N-N single bond is weaker and longer than that of 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

Correct answer
BBoth statement I and statement II are false
Step-by-step explanation
single bond weaker than due to more repulsion.
Bond length , 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.
