WebThe only hydrophobic group below is the methyl (CH 3 _3 3 start subscript, 3, end subscript) group, which is nonpolar. The remaining six functional groups in the table all have varying degrees of hydrophilic character. Webmolecules are attracted to, and dissolved in, a solvent that has similar polar (or nonpolar) character nonpolar if the + and - charges are evenly and symmetrically distributed throughout the molecule polar if more - charge is concentrated at one end of the molecule, and more + charge at the other end

WebEthyl oleate is a long-chain fatty acid ethyl ester resulting from the formal condensation of the carboxy group of oleic acid with the hydroxy group of ethanol. It has a role as a plant metabolite and an acaricide. It is functionally related to an oleic acid. WebThe difference, of course, is that the larger alcohols have larger nonpolar, hydrophobic regions in addition to their hydrophilic hydroxyl group. At about four or five carbons, the hydrophobic effect begins to overcome the hydrophilic effect, and water solubility is lost.
