What is correct increasing order of bond lengths of bond indicated as I , I I , I I I and I V in following compounds?
Options
- AI < I I < I I I < I V
- BI I < I I I < I V < I
- CI V < I I < I I I < I
- DI V < I < I I < I I I
Correct answer
D. I V < I < I I < I I I
Step-by-step solution
% S-character ∝ 1 Bond length in (ii) & (iii) , (ii) having (+) hyperconjugation so double bond character.
