Question

Rank the following compounds in order of decreasing acidity. Br ОН Br OH CI OH FF SH CI B A FF c D D>C>B>A A>B>CD OCD>A>B C>D>B>A

Answer 1

6:1 X +H А в A 3 cohich stabilizes. A and B are election withdrawing group -ve charge on oxygen: More electronegative is the A and B, more Stable is the anion. on acidic Strength depend Stability of anion. FCI > Bor electronegativity order of acidic Strength: DSC > B>A [so is more stable than o- so is larger thanol (A) is Correct option. Stability of olkene the 0:4 a Nomber of alpho hydrogen Substituent on alkene: C> A > B>D t Sonly 1 Jubstituent. 4 sulotituent (6) is the correct option. 0:3 (IV) Most Conjugated least double bond character in c=ó 6 ong , Nave number. DVR least Wave number. fraise the correcto option. 0:4 (B) y Hg Co Ac)2, Hao 2 NaBity, Nooh Markornikor addition of H and of without rearrangemet (B) is the correct option OH

05 Peak below 3000 of Confirm presence Carbon is sp3 C-H bond, where със — Н No H attached to spa hybridized Carbona ~ (D) is not possibl 3600 Confirm Peak between 3000 bond presence of -6-H - Peak around 1680-1650 Confirm Carbonyl group. ī Peak of on is present separately, that means Carboxylic acid is not there. (C) is the correct option.
