As you can see here this is the equation of acetic and stearic acid.it shows how they are different from each other. This is because acetic acid reacts much more exp[losively with water.
Acetic acid (ethanoic acid) is more polar. Carboxylic acid functional groups are more polarizing then Alcohol functional groups.
Polarity Ranking of the Functional Groups:
(most polar first)
Amide > Acid > Alcohol > Ketone ~ Aldehyde > Amine > Ester > Ether > Alkane
Yes silica is more polar then ethyl acetate . Deepak
Yes, ethyl acetate is more polar than toluene.
on basis of solubility in water. ethyl acetate.
Acetic acid is polar because it is asymmetrical meaning that dipole moment does not get cancel.
butyric acid
Cholesterol esters have a lower solubility in water than cholesterol and are more hydrophobic

Types of lipoproteins differ in density, lipid composition, and function. They include very-low-density lipoprotein (VLDL), low-density lipoprotein (LDL), and high-density lipoprotein (HDL). LDL's have a density of 1.006-1.063 g/mL, made up of 6% Triacylglycerol, 22% Phospholipids, 8% Cholesterol, 42% Cholesteryl esters, and 22% Protein. HDL's have a density of 1.063-1.210 g/mL, made up of 4% Triacylglycerol, 24% Phospholipids, 2% Cholesterol, 15% Cholesteryl esters, and 55% Protein.To summarize, LDLs have more lipid and less protein, therefore less dense. HDLs are protein rich and dense.Also, they differ in their function. LDL's deposit extra cholesterol in arteries, while HDL's move cholesterol to the liver.
Marine organisms living in polar regions have a very high proportion of cholesterol in membranes to keep the membranes more fluid and keep the molecules moving faster because in cold temperature, molecules move slower.
Hexane is a non-polar chain hydrocarbon; on the principle of "like dissolves like" hexane will dissolve other non-polar compounds quite well. Water is a polar molecule, as are all halogens as exemplified by the simplest common halogen of all, hydrochloric acid. Halogen acids, common refrigerants, even some anesthetics are all polar molecules and therefore dissolve fairly well in other polar liquids, including water.
