3. Show the steps necessary to transform the acid on the left into the compound on the right. Be sure to use SOCI2 a) -CHCHOCH Р-снсн. Сон Н.С-СНСH,CoСНB Н-С-СНCH,COН несиси вусая, b) Н.С-СНСH,CоН нсснсн 2он Н,С-СНСH,CNСАНЯ CH2CH2CH3 4. Number these in order of ease of hydrolysis. 1 =easiest to hydrolyze, 4 hardest to hydrolyze. сHсн2нся. сновсм, CH2CH2CNHC&Hs CHоёсн, CH3CH2CCI N=CCH3

Answer 1

A3 @ HG = CH CH C-on - H₂C = CH CH C" - CHiz now we since have to socl, use Converts Soch acid unto Eacid hallide H₂ C = CH CH, C-OH - 2 H C = CH CH, C-a & Hd + So now into use use desired to alcohol product transforms i H₂ C = CH CH, C-ci CH₂OH H C = CH CH C-OCH, (6) HC = CH CH₂ C-on H₂ C = Oncn, CNGH CH CH CHz first we use Soch to form acid hallide

HC = CH CH₂ Con Socks H, C = CH CH ₂ C -a + 30 g + Hol now we have acid hallide & We have to replace 'd' by. CH₂ CH CH - N - Colis hence this is a base & we can use 6 cachetty H₂ C = chcr, c-a H, C = CH CH, CNG HC=CH Сң си, з THCH Hence we get the = chcH, C-N-GHs CH₂ CH₂ CH3 Ans:4) Those compounds are - which follow SN because hydrolysis is an easily hydrolysed mechanion SN 1 reaction

Giren Compounds are che carica anar engus azcon CH₂ CH₂ cal CH₂ CH₂ CNH GHS (2) NEC Ch (3) си, ос. (на from the given compounds she is most Stable as Carbocation is stable then ② then 3 & then to because In 9 & ② resonance stablisation is done Hence the sequence is (4) > (2) > (3) > 1.
