Question #986051
How many sigma bonds are in acetaminophen (C8H9NO2)?
My textbook answer key says only 16 sigma and 4 pi bonds, but I keep on counting 20 sigma bonds because of the four unshown H atoms off of the aromatic. This is a picture of the skeletal structure: http://www.chem.purdue.edu/gchelp/116exams/e1f003.gif
