| Résumé : | Dielectric constant data have been obtained for the following compounds, pure and in benzene solution: four straight-chain heptanols, the n-heptaldehyde, the three ketones, the four chloro and four bromo derivatives and 1-iodo and 3-iodoheptane. From these data the electric moments have been determined. The position of the polar group in the chain in the case of the alcohols has been found to have no effect. In the case of the halogen derivatives, the moment is found to be the same for chloro, bromo and iodo compounds but a slightly smaller moment is obtained when the substituent is in the 1-position than when it is in either of the other positions. The electric moment characteristic of each of the groups, hydroxyl carbonyl and halogen, as shown in aliphatic compounds has been tabulated. |
