Question

please give me the order and explain why. thanks

10. (10 pts) Arrange the letters designating the five compounds shown below and labeled A-E in order of increasing acidity, i.e. least acidic on the far left---most acidic on the far right. A CH.-C. - E-OH B C-CH-¿-OH C CH₂-C-C-oh Br Br É Br Br CH₃-CH-(-OH & &-CH₂-C-oh Br H DLALELBSC

Answer 1

LOH A COH CH - C- A CH3 CH2-C-OH By Br Br I Br C - OH CHz CHy-c— ОН CH3 - C - HF E © CHO -OH e- С— ОН I Br Ans =) DSE< B < ACC compound 'e' e's most acidic because two strongly electronegative 'F' atoms are on Q-C (with respect to -COOH group) having strong - I effect. Compound D'is least acidic because no I effect is present in this molecule. Again two 'By' atoms (-I-effect) on a-c make the compound 'A' more acidic than 'B' (two Br atoms on 'B-e) and 'E' cone Br atom on ß-c).
