8) Circle the strongest acid (proton donor) in the following threesomes. (3pts) (a) H3C-C-OH CH3CH2-OH -o-CH H3C-C-O-CH3 ni ci vora (b) CO2H CO2H CO2H (c) CH3 CN

Answer 1

donors are those which relas es Strongest poston podton easily. Generally those lave election with drawing group leighly electre negative attack reclases atom proton eas asily

9 I amon among b) OH H.C-2-OH all there acids is the strongest proton donor than alcohol and ester because electron with d wi onggens present while esters are least acidie among acids and alcohols cl This is strongest because el is a st Strong election withdrawing guard and pulls election density towards itsey relase eas males -OH Proton to easily aree least acidic all there are benzoic acid -CH3 group is electron so it makes icult to relase while -CN is a 8 strong electron thus makes Ht releases so Ethers But have Hore different substituent donating geauf. so it makes dificult to selase proton worindiawiting groups thes make easy is strongest prolon donor -CooH so 10 Net
