Highly Soluble in Water:
* Sugars: Glucose, fructose, sucrose
* Alcohols: Ethanol, methanol, isopropanol
* Simple Acids: Acetic acid, citric acid
* Amines: Methylamine, ethylamine
* Amino Acids: Glycine, alanine, lysine
* Some Vitamins: Vitamin C (ascorbic acid)
Moderately Soluble in Water:
* Short-chain fatty acids: Butyric acid, propionic acid
* Some ketones: Acetone, methyl ethyl ketone
* Simple esters: Ethyl acetate, methyl benzoate
* Some aldehydes: Formaldehyde, acetaldehyde
* Some organic salts: Sodium acetate, potassium citrate
* Certain polyols: Glycerol, ethylene glycol
Slightly Soluble in Water:
* Long-chain fatty acids: Stearic acid, palmitic acid
* Aromatic hydrocarbons: Benzene, toluene
* Many lipids: Fats, oils, waxes
Insoluble in Water (but soluble in other solvents):
* Many lipids: Fats, oils, waxes (soluble in hexane, ether)
* Polymers: Polyethylene, polystyrene (soluble in specific solvents depending on the polymer)
* Resins: Natural and synthetic resins (solubility varies greatly)
Important Considerations:
* Solubility is affected by factors like temperature, pH, and the presence of other solutes.
* Organic compounds can exhibit varying degrees of solubility in different solvents.
* The terms "soluble" and "insoluble" are often relative, and there are many substances with intermediate solubilities.
This list is just a starting point. There are many other examples of soluble organics, and the field of organic chemistry is vast and complex.
