Question

ORGANIC CHEM.

Arrange in decreasing order of pKb

Options are:

(a) Q > S > P > R

(b) P > R > S > Q

(c) R > Q > P > S

(d) S > Q > P > R

Answer with explanation.

Answer 1

R is highly aicidic as electron density is more in r as f is electron withdrawing group so decrease density on R comp more as compare to p
we also know that aicidic strength is inversely proportional to pkb so
ans is c

Answer 2

Answer:

option c is correct answer
