Answer:
The order in which the orbitals is filled is 1s-2s-2p-3s-3p-4s-3d-4p-5s-4d-5p-6s-4f-5d-6p-7s-5f-6d-7p
Explanation:
S orbitals each hold two electrons, p orbitals hold 6, d orbitals hold 10, and f orbitals hold 14. 1s has the least energy and 7 p has the greatest energy, so the order in which they are filled is listed above.

You know that each carbon atom can take as much as 4 bonds with other elements. A hydrogen can only take one bond, while an oxygen can take 2. Thus, the chemical formula of H₂CO may be written as H₂C=O which is acetaldehyde. Acetaldehyde is an aldehyde. It has a higher vapor pressure because aldehydes have much stronger bonds than hydrogen bonds in alcohols. Hence, it would need a lot energy, thus higher vapor pressure, to break the bonds of an aldehyde than it would for an alcohol.
