Correlation between structure and normal boiling points of acyclic carbonyl compounds

Acyclic saturated and unsaturated carbonyl compounds (mono- and dialdehydes , mono- and diketones, keto aldehydes, and esters of monocarboxylic acids) with various degrees of branching but devoid of hydrogen bonding were inclu ded in a quantitative structure-property relationship study for correlating chemical structure with normal boiling points. Three separate correlations are presented in terms of five topological indices: for 127 mono- and dial dehydes and -ketones, for 73 esters, and for the combined set of all 200 ca rbonyl compounds. Standard deviations are lower than 7 degrees C.
