1)Give a chemical test that can be used to distinguis between separate samples of propanone and propanal. Give a suitable reagent for the test and describe what you would obsrve with propanone and with propanal. 2) Outline the reaction of propanone with the following reagents. Give the equation for the reaction, the conditions, and the name of the organic product. (i)Hydrogen cyanide (ii)dodium tetrahydridoborate(III) (sodium borohydride) (iii)what type of mechanism is this (iv) what feature of the carbonyl group makes this type of mechanism possible? Explain how this feature arises? 3)Three isomers A,B, and C have the molecular formula C4H8O. All three compouds give an orange precipitate with 2,4-dinitrophenylhydrazine reagent. B and C give a silver mirror when waremed in ammoniacal silver nitratesolution. Write the strcutural formulae of A,B and C.
