Question

can question A parts A4 (a and b) A5 and A6 be answered neatly and labled. with specifics in A5 and A6

Dale Tepot sub Partners NUCLEOPHILIC SUBSTITUTION A. Structural Effects on Sn1 and Sn2 Reactivity A1. In the following table, record the results of your group's experiments with the five alkyl halides and the two reagents, sodium iodide in acetone and alcoholic silver nitrate. Note the elapsed time required for turbidity to appear and for a precipitate to form. If you heated any of the test tubes, note the results. Compound Nal in Acetone AGNO3 Reaction time (s) Reaction time (s) C: 2:940 Sec 1-chlorobutane C:&1.35 1-bromobutane P.902.1 P: C 2-chlorobutane No n NO rxn P: c:4.3 s 2-chloro-2-methyl no rxn propane P:40.5 C: Ss.6 Benzyl choride C: o0sec P:240.4.5 cn. Based on your results, list the order of reactivity (from most reactive to least A2. reactive) of the four alkyl chlorides with each of the reagents. a.

Answer 1

A-4: (a) With Nal in acefone: 1- brombudeme ) - Chloro budem 2940 ser. 1800 sec (no rans o with AgNO3 in ethanol I bromobutere) Icehoroba As yes they A-46) agree with the expected outcome bared on fr2 recetin. In Sw2 reaction vale determin defents on the leaving group propensity. Here Br is good leaving group than ci so, rection time in case of t- Bowno butaine is less thom l- chlorobutene. 46. yes, the rescuts agreed with the Soil fethwey. As in snl bethway generation of consechin is the rete defanining step. so the generation of contreatin will be feste whore leaving group propensity is high a other way which con strongly bind to og and generele the cortocchin. So in case of 1 bronebeten recefin rete is generule the cartocchina s hoh higher -
