Questions: Isopropanol, (CH3)2CHOH, is an organic compound that is a common ingredient in many disinfectants. Which statement best describes an isopropanol molecule?
A hydrocarbon that is classified as an alkene because it has at least one double bond.
A hydrocarbon that is classified as an aromatic because it has a ring structure of six-alternating carbon-carbon single bonds and double bonds.
A small organic compound that will also mix with water because it contains a dipole moment in its chemical structure.
A large organic compound that will not dissolve in water because it is mostly nonpolar in its chemical structure.

Solution
Solution Steps
Step 1: Identify the Structure of Isopropanol
Isopropanol, also known as isopropyl alcohol, has the chemical formula \((\mathrm{CH}_3)_2\mathrm{CHOH}\). Its structure consists of a three-carbon chain with a hydroxyl group (-OH) attached to the middle carbon atom.
Step 2: Determine the Classification of Isopropanol
Isopropanol is not a hydrocarbon because it contains an oxygen atom in the hydroxyl group. It is an alcohol due to the presence of the -OH group.
Step 3: Evaluate the Statements
A hydrocarbon that is classified as an alkene because it has at least one double bond.
Incorrect. Isopropanol does not have any double bonds; it has single bonds and a hydroxyl group.
A hydrocarbon that is classified as an aromatic because it has a ring structure of six-alternating carbon-carbon single bonds and double bonds.
Incorrect. Isopropanol does not have a ring structure; it is a straight-chain molecule.
A small organic compound that will also mix with water because it contains a dipole moment in its chemical structure.
Correct. Isopropanol is a small organic molecule with a hydroxyl group, which is polar and can form hydrogen bonds with water, making it miscible with water.
A large organic compound that will not dissolve in water because it is mostly nonpolar in its chemical structure.
Incorrect. Isopropanol is a small molecule and is polar due to the hydroxyl group, allowing it to dissolve in water.
Final Answer
\(\boxed{\text{A small organic compound that will also mix with water because it contains a dipole moment in its chemical structure.}}\)
