But-
The prefix "but-" indicates a molecule with 4 carbon atoms. Examples include butane (C4H10) and butene (C4H8).
There is NO 'one single bond' organic molecule possible.The simplest 'single bond' organic molecule is methane (CH4) with 4 (not one) single bonds (between central C and 4 H atoms).The only possible 'one double bond' organic molecule is carbon monoxide (C=O)
Lipids: Carbon, Hydrogen and Oxygen - monomers are glycerol and fatty acids Proteins - Carbon, Hydrogen, Oxygen and Nitrogen - monomers are amino acids Carbs - No Phosphate. Carbon, Hydrogen and Oxygen - H:O ratio is 2:1 - monomers are monosaccharides (may have a ring structure) Nucleic Acides - examples are dna and rna. Carbon, Hydrogen, Oxygen, Nitrogen and Phosphate - monomers are nucleotides (sugar, phosphate, nitrogen base)

There are 4 phosphorus atoms in a molecule of P4. Each molecule consists of 4 phosphorus atoms bonded together.

Unsaturated hydrocarbon is the name of a type of organic molecule in organic chemistry, that contains a chain of carbons. "Unsaturated" refers to the fact that each of the carbons bonds aren't with 4 separate molecules, but can, instead have double or triple bonds.A hydrocarbon in which valencies of carbon are not satisfied by single covalent bonds are unsaturated hydrocarbons.

Carbon atoms typically form four bonds in organic molecules to achieve a stable electron configuration. Examples of molecules that show an appropriate number of bonds around each carbon atom include methane (CH4), ethane (C2H6), and propane (C3H8).
There are four nitrogen atoms in this compound (C8H10N4O2).
