Abstract
Dielectric relaxation studies of alkyl (methyl, ethyl, and butyl) methacrylates with primary alcohols (1-propanol, 1-pentanol, 1-heptanol, and 1-octanol) at 9.84 GHz have been studied in benzene at 298 K. The results show that the most likely association between alcohol and ester is 1 : 1 complex through the free hydroxyl group of the alcohol and the carbonyl group of ester and the alkyl chain-length of both the alcohols and esters plays an important role in the determination of the strength of hydrogen bond (O–H:O=C) formed. Comparative study of free energy of activation for the dielectric relaxation and viscous flow suggest the fact that the process of viscous flow involves greater interference by neighbors than does dielectric relaxation, as the latter takes place by rotation only whereas the viscous flow involves both the rotational and translational forms of motion.
