Question

Match the following under chemical compounds under Column I with their respective chemical tests under Column II

Column I  Compounds		Column II  Chemical tests
A	Quinine	I	Borntrager's
B	Digitoxin	II	Thallequin
C	Atropine	III	Vitali Morin
D	Sennosides	IV	Keller killiani

Choose the correct answer from the options given below :

• A. (A)-(II), (B)-(IV), (C)-(III), (D)-(I)
• B. (A)-(III), (B)-(IV), (C)-(II), (D)-(I)
• C. (A)-(I). (B)-(II), (C)-(III), (D)-(IV)
• D. (A)-(IV), (B)-(III), (C)-(II), (D)-(I)

Answer 1

The Correct Option is A

To solve the given problem, we need to match the chemical compounds listed in Column I with their respective chemical tests in Column II. Let's break down the associations: 

1. Quinine: This alkaloid is known to respond to the Thallequin Test (Test II). This test involves the use of bromine water and ammonia which yield a green color if quinine is present.
2. Digitoxin: This cardiac glycoside reacts with the Keller-Kiliani Test (Test IV). This test identifies the presence of digitoxin by causing a blue or green color to appear when digitoxin reacts with a mixture of ferric chloride and acetic acid.
3. Atropine: Identified by the Vitali-Morin Test (Test III), which is a test for tropane alkaloids that produces a violet color if atropine is present upon treatment with fuming nitric acid and alcoholic potassium hydroxide.
4. Sennosides: These compounds are detected using Borntrager's Test (Test I). This test is used for anthraquinone derivatives, producing a pink or red color after treating the sample with an aqueous solvent and an alkaline solution.

From this analysis, the correct matching becomes:

A	Quinine	II	Thallequin
B	Digitoxin	IV	Keller-Kiliani
C	Atropine	III	Vitali Morin
D	Sennosides	I	Borntrager's

Thus, the correct answer is:

(A)-(II), (B)-(IV), (C)-(III), (D)-(I)
