Question #b6abb

Answer 1

Process of elimination (see below)

Explanation:

Isomers of a chemical formula, such as `C_4H_10O`, maintain the same chemical formula, but have different structural features. Note that `C_4H_10O` is very similar to `C_4H_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_4H_10O` 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 (`OH` group) and ethers (`CO` branch).

Here is a video on how to draw them:
