Explain the meaning of partition in chromatography.
Explain the meaning of adsorption in chromatography.
Ring the spot that did not dissolve in solvent 1.
Using solvent 1, label the spots that were not resolved as A and B.
Deduce the identity of $X$, and give a reason.
When the relative heights of the $M$ and $M+1$ peaks are 9 and 0.3 respectively, calculate the value of $p$. Use that result together with the $m/e$ value of the molecular ion peak to calculate the value of $q$, and hence the compound’s molecular formula. Show your working.
Suggest a formula for the ion that gives rise to the peak labelled $R$.
In the fragmentation of alcohols that takes place in a mass spectrometer, small stable neutral molecules can sometimes be formed. Suggest the identity of one such molecule, with an $M_r$ less than 30.
