cations that form weakly charged complexes in HCL would have a high rf value?
Homework Answers
The more highly charged cations are more extensively hydrated in aqueous solution and the waters of hydration should be even more difficult to replace. It is interesting that HDPM retains the rare earths, yttrium, scandium and the quadrivalent elements better than TOPO or TBP while TOPO seems slightly superior for zinc, cadmium and mercury as well as cobalt, copper, gallium, indium and possibly iron(III).
The Rf values of zero signify a rather low partition coefficient into the TOPO or HDPM phase. The larger values suggest the partition coefficient is high. It is to be noted that the elements known to form strong chloride complexes have higher Rf values. It would also appear HDPM is a more powerful extractant for the lanthanides than TOPO from 6M hydrochloric acid.

The H NMR spectra of amides (1) have some interesting quirks. One quirk is that the N-H protons of primary and secondary amides (e.g. 2) are quite broad and appear at relatively high but variable chemical shifts (5-9 ppm). Another "quirk" is that identical N-R groups (e.g R2 groups in 3) can appear at different chemical shifts even though the same groups in a ketone analog...
