How many σ bonds and π bonds exist in the molecule?

Question

How many σ bonds and π bonds exist in the molecule: C6H7HO ?

Answer 1

To make this easy, I draw out the molecule. Keep in mind that Carbon must have 4 bonds, Hydrogen can only have one bond, and Oxygen can only have 2 bonds. As long as you follow these rules, even though you may place the hydrogens and double bonds in different positions than I do, you will have the same number of sigma and pi bonds. A sigma bond, the strongest bond, is formed by the head-on overlapping of atomic orbitals. Therefore, every bond will have at least one sigma bond. A pi bond is formed by the sideways or lateral overlapping of atomic orbitals. Therefore, they will be the other type of bonds in either a double or triple bond. To answer your question, this molecule has 13 sigma bonds and three pi bonds.
