JEE PYQ: Chemistry In Everyday Life Question 19
Question 19 - 2019 (09 Jan Shift 1)
The correct match between Item-I and Item-II is:
Item-I (drug) — Item-II (test) A. Chloroxylenol — P. Carbylamine test B. Norethindrone — Q. Sodium hydrogencarbonate test C. Sulphapyridine — R. Ferric chloride test D. Penicillin — S. Bayer’s test
(a) $A \to R$; $B \to P$; $C \to S$; $D \to Q$ (b) $A \to Q$; $B \to S$; $C \to P$; $D \to R$ (c) $A \to R$; $B \to S$; $C \to P$; $D \to Q$ (d) $A \to Q$; $B \to P$; $C \to S$; $D \to R$
Show Answer
Answer: (c)
Solution
Chloroxylenol contains phenolic group so it gives positive ferric chloride test (R). Norethindrone has double bond, thus it will give Bayer’s test (S). Sulphapyridine contains $-\text{NH}_2$ group so it gives carbylamine test (P). Penicillin contains $-\text{COOH}$ group so it will give sodium hydrogen carbonate ($\text{NaHCO}_3$) test (Q).
