# how many sigma and pi bonds are in CH3CHCHCO2H?

0

• So far, no one has gotten this correct. I’ll diagram on here as best I can.

C – C = C – C=O

So i put the carbons up there with the double bonds. We have two double bonds, one between two carbons and one between a carbon and an oxygen.

The first carbon also has 3 H’s on it,

Second has 1 H

Third has 1 H

and the Fourth carbon also has an -O-H on it.

Remember each double bond also has a sigma bond in it.

There are 11 sigma bonds and 2 Pi bonds.

• There are 11 sigma bonds and 2 Pi bonds.

• The simplest way to figure this one out would be to draw the Lewis structure for your molecule there. Every single bond is a sigma bond. As for double and triple bonds, each bond beyond the first is a pi bond.

• My answer is 9 sigma bond, 3 pi bonds

Source(s): Myself and some piece of paper with the diagram
• Sigma bonds are single bonds and pi bonds are double bonds.

So 11 sigma bonds and 2 pi bonds
