Class of hydrophobic ?

The class of hydrophobic molecules includes lipids, fatty acids, and nonpolar amino acids. These molecules are insoluble in water and tend to aggregate together in order to minimize contact with water molecules.

Classes of Hydrophobic Compounds:

1. Alkanes
- Saturated hydrocarbons (contain only single bonds)
- Branched or unbranched
- Examples: methane, propane, hexane

2. Cycloalkanes
- Cyclic alkanes
- Examples: cyclopropane, cyclopentane, cyclohexane

3. Arenes (Aromatic Compounds)
- Compounds containing a benzene ring (a cyclic, conjugated system with six carbon atoms)
- Examples: benzene, toluene, xylene

4. Haloalkanes
- Alkanes with one or more hydrogen atoms replaced by halogen atoms (F, Cl, Br, I)
- Examples: chloromethane, chloroform, bromobenzene

5. Alkenes
- Unsaturated hydrocarbons containing at least one double bond
- Examples: ethene, propene, butene

6. Alkynes
- Unsaturated hydrocarbons containing at least one triple bond
- Examples: ethyne, propyne, butyne

7. Alcohols (Polar Protic)
- Compounds containing a hydroxyl group (-OH)
- Can form hydrogen bonds
- Become less hydrophobic with increasing molecular weight

8. Amines
- Organic compounds containing a nitrogen atom
- Can form hydrogen bonds
- Become less hydrophobic with increasing molecular weight

9. Ethers
- Compounds containing an oxygen atom bonded to two carbon atoms
- Polar, but cannot form hydrogen bonds

10. Esters
- Compounds containing a carbonyl group (C=O) bonded to an oxygen atom and an alkyl group
- Polar, but cannot form hydrogen bonds

11. Carboxylic Acids (Polar Protic)
- Compounds containing a carboxyl group (COOH)
- Can form hydrogen bonds
- Become more hydrophobic with increasing molecular weight

12. Amides
- Compounds containing a carbonyl group (C=O) bonded to a nitrogen atom
- Polar, but cannot form hydrogen bonds
