How many sigma (σ) bonds and pi (π) bonds are in acetic acid?
Question:
a.eight σ and zero π
b.six σ and one π
c.six σ and two π
d.eight σ and one π
e.seven σ and one π
Answer:
Acetic acid has three C-H bonds, one C-C bond, one C-O bond, and one O-H bond. These are all single bonds, and they are all sigma.
There is also a C=O double bond, which counts as one sigma and one pi bond.
So altogether you have 7 sigma and 1 pi.
CH3C(=O)-OH
7 sigma 1 pi
e)
CH3COOH has 7 sigma bonds, they are all the C-H bonds (3 total), C-C bond (1 total), C-O bond (1 total), O-H bond (1 total) and one from the C=O.
It has 1 pi bond which is the C=O bond. So the answer is E. I hope this helps.
