A chemical reaction produces formaldehyde, with a chemical formula of CH2O. Carbon is in Group 4A, oxygen is in Group 6A, and hydrogen is in Group 1A on the periodic table. In one to two sentences, describe the bonds in a molecule of formaldehyde in terms of valence electrons. (2 points)
In a molecule of formaldehyde, carbon forms covalent bonds with two hydrogen atoms by sharing valence electrons, while it also forms a double bond with oxygen by sharing two pairs of valence electrons.
