Experimental results of dielectric investigations of X-band microwave bench at 9.86 Ghz for amides (Foramide, N-methylforamide and N, N-dimethylformaide) with 1-propanol have been studied in carbon tetrachloride at 303 K. The relaxation time has been determined using the measured dielectric data. The results show that carbonyl group of amide and alkyl chain-length of both the alcohols and amides plays an important role in the determination of the strength of hydrogen bond (O-H:O=C) formed. The most likely association between alcohol and amides is 1:1 complex through the free hydroxyl group of the alcohol and the carbonyl group of amide and the results show a linear dependence of relaxation time on alkyl chain length of alcohols and alkyl amides and also on the nature of the solvent.
