Dipole moments and conformations of some substituted benzaldehydes

Abstract

Experimental electric dipole moments are reported for a number of substituted benzaldehydes (o-, m-, and p-XC₆H₄CHO; X = NO₂, CN, F, Br) as solutes in carbon tetrachloride or benzene at 25°C. Analysis of results yields information concerning the preferred conformations of thesemolecules.
