Question

How many sigma and pi bonds are in acetic acid, `CH_3CO_2H`?

Answer 1

This is acetic acid,

Each single bond has a `sigma` bond between two hybridized orbitals of the carbons. Each double bond has a `sigma` and `pi` bond between the two hybridized orbitals and unoccupied p-orbital in the carbon atom(s) (and oxygen in this case).

Hence, acetic acid has:

3 `sigma` bonds, and

1 `pi` bond.
