Answer 1

Poort- & short answer 16. label the following 10 Jeast audic compounds (1-4) as being most acidic HO HO 4 - Ethoxy phonol 4-Nitrophenol 1-C4-hydrony N-(4-hydroxy phory pe phenyl)-2-methyl acetamide pka 10.2 propan-i-one 7.2 4. C Anst * Audity phenol depends upon the stability of phononoscido fon formed as a result of resonance. * Electron withdrawing groups such as NOZ, CN, CHO etc., which stabilize the phenoude ion by dispersing the negout ive cheerge relative to phenol increase the aud strength 05 phocols. Most electron with drawing group is - NO2 electron donating group - NH > O-CH3 Therefore, the order of aldity of substituted phends :- HO 90 "amo, but shor shume 9.
