consider the five cyclic compounds a b c d and e do not write outside the box cyclohexane cyclohexanol cyclohexanone oh br cyclohexene bromocyclohexane a the infrared spectra of compounds a b c and d are shown opposite write the correct letter a b c or d in the box next to each spectrum you may find it helpful to refer to table on the data sheet wmp jan chem do not write outside the box a i transmittance wavenumber cm mark a ii transmittance wavenumber cm mark a iii transmittance a iv transmittance wavenumber cm mark wavenumber cm question continues on the next page mark turn over wmp jan chem do not write outside the box b a simple chemical test can be used to distinguish between cyclohexane a and cyclohexene d give a reagent for this test and state what you would observe with each compound marks extra space c cyclohexanol b can be converted into cyclohexanone c give a reagent or combination of reagents that can be used for this reaction and state the type of reaction state the class of alcohols to which cyclohexanol belongs marks extra space wmp jan chem d cyclohexane a can be converted into bromocyclohexane e by a reaction that is similar to the reaction of methane either with chlorine or with bromine do not write outside the box name and outline a mechanism for the reaction of methane ch with bromine to form bromomethane ch br give one condition for this reaction to occur write an equation for each step in your mechanism marks extra space end of questions wmp jan chem
