WebAug 17, 2024 · Chlorine atoms are more electronegative than carbon and hydrogen atoms and they are located at three of the pyramid’s vertices, pulling the negative charge in their direction, resulting in a polar molecule with a downward dipole. The dipole moment of CHCl 3 is 1.15 D. Despite this, it is nonpolar. Why?
Cyclohexane is a cycloalkane with the molecular formula C6H12. Cyclohexane is non-polar. Cyclohexane is a colourless, flammable liquid with a distinctive detergent-like odor, reminiscent of cleaning products (in which it is sometimes used). Cyclohexane is mainly used for the industrial production of adipic acid and caprolactam, which are precursors to nylon. Cyclohexyl (C6H11) is the alkyl substituent of cyclohexane and is abbreviated Cy. WebNov 16, 2024 · The unpolar stationary phase (SP) consists of silica microparticles functionalized with hydrophobic or mixed ligands—C30, C18, C8 hydrocarbon chains or cyano, phenyl, amino derivatives (listed in the order of decreasing hydrophobicity).
