Question

In the Victor-Meyer test, the color given by 1°, 2°, and 3° alcohols are respectively:

• A. Red, colorless, blue
• B. Red, blue, colorless
• C. Colorless, red, blue
• D. Red, blue, violet

Hint:

Victor-Meyer test is used to distinguish between different types of alcohols based on color changes.

Answer 1

The Correct Option is B

Step 1: Comprehending the Victor-Meyer Test
The Victor-Meyer test distinguishes between primary, secondary, and tertiary alcohols. This distinction is achieved by observing their distinct reactions when treated with HI, AgNOsubscript{2}, and KOH.
Step 2: Observing Color Formation
Primary Alcohols: Result in the formation of a red nitroalkane.
Secondary Alcohols: Produce a blue pseudonitrole.
Tertiary Alcohols: Do not yield a stable colored compound and remain colorless.
Final Answer: The expected colors for primary, secondary, and tertiary alcohols are Red, Blue, and Colorless, respectively.
