How might you distinguish between a primary and secondary alcohol?

Warm and distill with acidified pottasium dichromate. Then test with tollens reagent. The acidified pottasium dichromate will have oxidised the primary alcohol to an aldehyde, which will form a silver mirror with Tollen's reagent. The secondary alcohol will have been oxidised to a ketone, which does not react with Tollen's reagent.

Calculate the empirical and molecular formula of unknown compound A which gave an m/z of 181 in the mass spectrum for the molecular ion peak. Elemental analysis by combustion shows the compound is C 53%, O 35.4%, H 3.9% and N 7.7%.


Name and explain briefly the main stages of mass spectroscopy.


What is the difference between Sn1 and Sn2 reactions?


The equilibrium N2O4 (g) -->--< 2NO2 (g) is set up when N2O4 dissociates. When 0.0370 moles of N2O4 dissociates at 25 degrees in a 0.5dm3 sealed container, 0.0310 moles of N2O4 remains at equilibrium. Calculate the value of Kc for this reaction.
