What are the number of protons and electrons for each of the following: Mg2+ Nat CI H*

Background: Given an unknown mixture which contains either two or three of the following liquids: tetrahydrofuran (THF), cyclohexane, toluene, and o-xylene. While the order that the compounds leave the column is not always obvious, the column we are using is a polar environment and therefore we would expect less polar (lower boiling) compounds to spend the least time in the column. In order to qualitatively confirm the identity of the peaks, you will make five different samples to analyze on the gas chromatograph: (a) your unknown, (b) unknown + THF, (c) unknown + cyclohexane, (d) unknown + toluene, and (e) unknown + o-xylene. Any new peak that appearsin relation to your unknown sample indicates that compound is not present in your unknown; furthermore, an increase in the size of a peak present in your unknown identifies that compound as a component of the mixture. Although not completely accurate, the areas of the peaks in your unknown will allow you to find the approximate percentage…

What is the unknown?

IR must have an analysis of the functional groups, or lack thereof, to support the identification of the unknowns.
