Not Medical Advice: Acetaminophen has 4 pi bonds and 16 sigma bonds (20 sigma bonds including the four unshown H atoms off of the aromatic).
Sigma bond is a covalent bond resulting from the formation of a molecular orbital by the end-to-end overlap of atomic orbitals, denoted by the symbol σ.
Pi bond is a covalent bond resulting from the formation of a molecular orbital by side-to-side overlap of atomic orbitals along a plane perpendicular to a line connecting the nuclei of the atoms, denoted by the symbol π.
Note: A single bond such as (C-H) has one sigma bond whereas a double (C=C) and triple (C≡C) bond has one sigma bond with remaining being pi bonds.
Chemistry is a subject that is often studied alongside Physics. However, it is important to remember that the two subjects are very different.
