[1] Salts and esters of caproic acid are known as caproates or hexanoates. Polar "In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. 2-Ethylhexyl hexanoate # Its asymmetrically placed carboxylic acid group and hydroxyl group cause it to have a net dipole moment, which grants it its polarity. In phenol OH group is present on benzene ring . The primary use of caproic acid is in the manufacture of its esters for use as artificial flavors, and in the manufacture of hexyl derivatives, such as hexylphenols. I have read that it is insoluable in water but i am not sure why. (d) (i) H 3 BO 3 = Equally Acid NH 3 =Equally Basic; H 2 BO 3-=Equally Basic NH 4 + =Equally Acidic (ii) The reaction equilibrium does not lie to either side. What we can hence infer (albeit very generally) from the table of DC values is that... 2 solvents far apart in DC values are probably immiscible. HELP! . it's symmetrical, but i read somewhere its polar, and somewhere else that its non polar.
