Question

drag each tile to the correct image. match each hydrocarbon class to its structure. carboxylic acid amine halocarbon alcohol

Explanation:

1. Amine: The first structure has an $\ce{-NH2}$ group, which is characteristic of amines (compounds with $\ce{-NH2}$, $\ce{-NHR}$, or $\ce{-NR2}$ groups).
2. Alcohol: The second structure has an $\ce{-OH}$ group bonded to a carbon, which defines an alcohol (hydroxyl group, $\ce{-OH}$, on a carbon).
3. Carboxylic Acid: The third structure has a $\ce{-COOH}$ group (carbonyl $\ce{C=O}$ plus hydroxyl $\ce{-OH}$ on the same carbon), typical of carboxylic acids.
4. Halocarbon: The fourth structure has a $\ce{-Cl}$ (halogen) bonded to a carbon, so it is a halocarbon (compound with a halogen atom replacing a hydrogen in a hydrocarbon).

Answer:

• First structure (with $\ce{NH2}$): amine
• Second structure (with $\ce{OH}$): alcohol
• Third structure (with $\ce{COOH}$): carboxylic acid
• Fourth structure (with $\ce{Cl}$): halocarbon
