Question

For compounds ,
A : Tetracuanoethern
B : Carbon dioxide
C: Benzene
D : 1 , 3-Butaidene .
Ratio of `sigma` and ` pi` bonds is in order :
A. A: Tetracynoethene
B. B: Carbon dioxide
C. C:Benzene
D. D , 1, 3 -Butadiene

Answer 1

Correct Answer - A
`C_2(CN)_4` has `underset(("Ratio 1")) (9sigma, 9pi, CO_2) hasunderset(("Ratio 1"))(2 sigma , 2 pi)`
Benzene has `underset("(Ratio 4)")(12 sigma, 3pi, 1, 3)`-butadiene has `underset("(Ratio 4.5)")(9 sigma, 2pi)`
