Chloro heptane

Three of the corresponding chlorides, 2-chloro-, 3-chloro- and 4-chloro-heptane, and the four bromides have been synthesized. Great care was taken in the preparation of these compounds to avoid any shift of position in the chain. Additional compounds are to be studied. 

In the chlorides and bromides it is seen that in the 2-, 3-, 4-positions the dipole moment is practically independent of the position in the chain. In i-bromo-heptane the dipole moment is slightly smaller than for the other bromides. The i-chloro-heptane will be investigated for comparison. The dipole moment is the same for the chloro- and bromo-derivatives of the aliphatic compounds, as...
