JEE PYQ: General Organic Chemistry Question 22
Question 22 - 2020 (05 Sep Shift 1)
The increasing order of the acidity of the $\alpha$-hydrogen of the following compounds is:
(A) $\text{PhCH}_2\text{COCH}_2\text{Ph}$ (B) $\text{PhCOCH}_2\text{COPh}$ (C) $\text{CH}_3\text{COCH}_2\text{COOCH}_3$ (D) $\text{CH}_3\text{COCH}_2\text{CONMe}_2$
(1) (D) < (C) < (A) < (B)
(2) (B) < (C) < (A) < (D)
(3) (A) < (C) < (B) < (D)
(4) (C) < (A) < (B) < (D)
Show Answer
Answer: (1)
Solution
Acidity $\propto$ stability of conjugate base. Thus increasing order of acidity is D < C < A < B.
