Given below are two statements Statement I : The C-C single bond is stronger and smaller than that of S i − S i single bond Statement II : On moving down the group in Group 14, the stability of M X 2

Question

Given below are two statements
Statement I : The C-C single bond is stronger and smaller than that of $S i - S i$ single bond
Statement II : On moving down the group in Group 14, the stability of $M X_{2}$ type compound increases(where $M$ = C, Si, Ge, Sn, Pb ; $X$ = Cl, Br, I)
In the light of above statements, choose the correct answer from the options given below

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.
