Hansen solubility parameter (HSP) to support our hypothesis (Table and Figure ). HSP 3D space (hydrogen bonding, polarity and dispersion) indicates that CN (2.5, 4.9, 20.5) has the largest HSP distance (Ra = 9.71) to the side chain (0, 0, 16.5), whereas decane (0, 0, 15.7) gives the smallest Ra = 1.60 due to its aliphatic nature. This supports our claim that decane only selectively dissolves side chain whereas CN is the poorest solvent for those aliphatic side chains.
