Study of some dipolar complexes involving long chain aliphatic alcohols

Abstract

The mechanism of 1:1 dipolar complexation of some long-chain aliphatic alcohols with chlorobenzene and acetic acids in a non-polar medium is studied. The interaction dipole moment △→µ, the excess molar polarization ΔP and apparent complex formation constantKapp are evaluated following two independent methods. It is observed from the value of △→µ that the complex formation is mostly due to polarization interaction and is of the same type as involving lower alcohols. ΔP andKapp are, however, of different nature compared to those in lower alcohols suggesting that the unlike molecules form relatively stable linear linkage resulting in antiparallel orientation prior to forming complexes.
