Which of the following reactions will proceed as written? CIC. 8. Rank the following in number order of increasing acidity (least acidic is #1): Ben de opening somente

Answer 1

5-) Ans: 1. Nastly CH3CO₂ CH3 2. thot no reaction. because Nasty & weak reducing agent it doesn't reduce the Ester. La Altly strong reducing agent it reduces Ester to alcohol - I Li Allty CH 3 C CH 2 CH3 CH₃-CH2-OH 2-40t 1. Nabty 2. Hot o rcla ng Br olt Olt CH3 City-city H - 2.100 2 ito . Elechon donating groups as Bensene group increases the reactivity in EAS (Electroplatre angl substitutions ) reaction here. CH3 СЊЕ enzene mo a) A>c>D>B. because-014 group has the effect it denate electron to benzene more so it is more reach the . -CH3 is tI-E group dess donate elechon density to benzene Compare to the group. CHF is little bit more reactine the & substituted benzene. (-me groups) Tule

7. here only this reaction proceeds. Aldy CH₃ cod + Alda - CH Co group so reaction 7 here Nos Electron withdrawing - not proceeds. * + Ctycoms 6 + ch co C NHEC. . ( different product formed ] not proceed at akylation on benzene) لیے یه مهام ده انار کا د OH Alah no reaction here-OH can salt form with 8. here the acidity of the below molecules depend upon the Corrugated in stability Election with drawing groups increases Abdalis, Electron donating groups decreases Acidity EDG OH Ovo Loh Ewa Ewa (para) Ewa (metal EDG frshest order is least TOH CO" DEL 011
