Process of elimination (see below)

#### Explanation:

Isomers of a chemical formula, such as ${C}_{4} {H}_{10} O$, maintain the same chemical formula, but have different structural features. Note that ${C}_{4} {H}_{10} O$ is very similar to ${C}_{4} {H}_{10}$ (Butane). Also note that for every double bond or ring in a formula, you lose 2 Hydrogen atoms.

Because having 10 Hydrogens and an Oxygen atom will have taken up all the free spots, we say that ${C}_{4} {H}_{10} O$ is saturated. Therefore, you do not have to worry about double bonds or rings.

Oxygen is a single bond. The only functional groups with a single bond are the alcohols ($O H$ group) and ethers ($C O$ branch).

Here is a video on how to draw them:
