Question

Identify the name of \(\text{CH}_{3}\text{CH}_{2}\text{OH}\) according to carbinol system .

• A. Methyl carbinol
• B. Ethyl carbinol
• C. Carbinol
• D. Ethanol

Hint:

In the carbinol system, methanol is carbinol and other alcohols are named as substituted carbinols.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept
In the carbinol system, methanol \(\text{CH}_{3}\text{OH}\) is called carbinol.
Other alcohols are named as carbinol with groups replacing hydrogen atoms of the \(\text{CH}_{3}\) part.

Step 2: Apply to ethanol
\(\text{CH}_{3}\text{CH}_{2}\text{OH}\) can be written as \(\text{CH}_{3}\text{-CH}_{2}\text{OH}\).
Here one hydrogen of the carbinol carbon is replaced by a methyl group.

Step 3: Name
So the compound is methyl carbinol.

Final Answer:
Ethanol is called methyl carbinol in the carbinol system. \[ \boxed{\text{(A) }\text{Methyl carbinol}} \]
