If the number of σ and π bonds in vinyl acetate are x and y...

If the number of σ\sigma and π\pi bonds in vinyl acetate are x and y respectively. What is the sum of x + y?

Correct answer

13

Step-by-step solution

Vinyl acetate has following structure
Cσ∣σ∣HH=πσC∣σH−σO−σCσ∣∣πO−C∣σσ∣HH−σH\overset{H}{\mathop{\mathop{\overset{\sigma |}{C}}_{\sigma |}}_{H}}\overset{\sigma}{\mathop{=}_{\pi}}\overset{H}{\overset{| \sigma}{C}}\mathop{-}_{\sigma}O\mathop{-}_{\sigma}\overset{O}{\overset{\sigma | | \pi}{C}} - \overset{H}{\mathop{\mathop{\overset{| \sigma}{C}}_{\sigma |}}_{H}}\mathop{-}_{\sigma}H
Total σ\sigma bond = x = 11
Total π\pi bond = y = 2
Total sum x + y = 11 + 2 = 13
