From part a : answer the question Questions1. Give two qualitative observations for eachsample upon closer examination of therespective photos.2. Sample Four was the only sample thatcontained an odour. What does this suggestabout the ease with which the particles canleave the solid with respect to the strengthof the intermolecular forces of attractionbetween the particles? (3. Which sample has mobie electrons forwhich to conduct electricity?4. Sample Four was the only one that wassoluble in a nonpolar solvent. What doesthis suggest about the polarity of themolecule in Sample Four?5. Sample One was soluble in water and in itsmolten state conducted electricity, but in itssolid state it did not conduct electricity.Electrons only flow in solids to producecurrent electricity. What types of particlesdoes the experimental evidence point to themakeup of this sample? (.6. What evidence is there to support theformation of ionic or molecular liquids ofnonpolar crystals?7. What could you deduce about the strengthof the forces of attraction between theparticles, in Sample 3, compared to theother samples? (1 mark)8. Give 3 more physical tests to help you inyour analysis of these samples and theirsubsequent identification. You are a chemist working in a laboratorywhere unknown samples are given to you totest and identify. Your first assignment is toidentify five unknown samples and state theirrespective type of crystalline solid. Theexperimental results are for you to examineand make your final conclusions.Samples:Sample 1Sample 2Sample 3Sample 4Part A- Chemical AnalysesIn addition to the visual observations you canmake from the photos of the samples, thefollowing results are from analyses of thesamples:Sample OneOdour- OdourlessSolubility in water- solubleSolubility in hexane- insolubleElectrical conductivity of solid- no conductionElectrical conductivity in molten state-conductsSample TwoOdour- OdourlessSolubility in water- insolubleSolubility in hexane- insolubleElectrical conductivity of solid- conductselectricityElectrical conductivity in molten state-conductsSample ThreeOdour- OdourlessSolubility in water- insolubleSolubility in hexane- insolubleElectrical conductivity of solid- no conductionElectrical conductivity in molten state-melting point is too high.

Questions 1. Give two qualitative observations for each sample upon closer examination of the respective photos. 2. Sample Four was the only sample that contained an odour. What does this suggest about the ease with which the particles can leave the solid with respect to the strength of the intermolecular forces of attraction between the particles? ( 3. Which sample has mobine electrons for which to conduct electricity? 4. Sample Four was the only one that was soluble in a nonpolar solvent. What does this suggest about the polarity of the molecule in Sample Four? 5. Sample One was soluble in water and in its molten state conducted electricity, but in its solid state it did not conduct electricity. Electrons only flow in solids to produce current electricity.
