Degrees of association of n-pentyl lithium and n-octyl lithium in benzene
Abstract
The degrees of association of n-pentyl lithium and n-octyl lithium in benzene at 30°C have been measured using the method of vapour pressure lowering. The value from n-pentyl lithium is 6.00 ± 0.09 [degrees of freedom (D.F.)]= 13]; the value for n-octyl lithium is 5.953 ± 0.016 (D.F. = 9). It is argued that the two compounds exist predominantly as hexamers in solution.
