However, a bond between the carbon atom and an oxygen atom has a bond order of 3/2 (resonance between a single and a double bond) and requires more room than a pure single bond. Explain How do I know? No special bond order formula is usually required: A single bond has a bond order of 1, a double bond has a bond order of 2 and a triple bond has a bond order of 3. In H 3 PO 4, all oxygen atoms have a formal charge of zero. If youre looking for the formal charge of the Molecule HCO2- then its just the -1.
