INTERFACIAL TENSION AND MOLECULAR INTERACTION

Interacial tension measurements indicate molecular interaction through H- bond between iso-­amyl acetate and chloroform, aniline, methylaniline, methyl salicylate or isoamyl alcohol. Such as interaction is not evident between isoamyl acetate and benzene, nitrobenzene, chlorobenzene, toluene, heptane, carbon tetrachloride or dimethylaniline. It is also observed between isoamyl alcohol and methylaniline or chloroform, when two liquids are mixed in certain proportions. Palmitic and lauric acids, cetyl alcohol and citronelol indicate the same behaviour as that of isoamyl acetate, when mixed with isoamyl alcohol ; so the fatty acid, alcohol or a constituent present in oil lemon should have a H-bond structure as that of isoamyl acetate
