Question

The formula of ethyl carbinol is

• A. \(CH_3OH\)
• B. \(CH_3CH_2OH\)
• C. \(CH_3CH(OH)CH_3\)
• D. \((CH_3)_3COH\)

Hint:

Old nomenclature: ethyl carbinol corresponds to 2-propanol i.e., \(CH_3CH(OH)CH_3\).

Answer 1

The Correct Option is C

Step 1: Meaning of carbinol.
Carbinol is old name for methanol.
Substituted carbinols are named depending on groups attached to carbon having \(-OH\).
Step 2: Ethyl carbinol structure.
Ethyl carbinol means one ethyl group attached to the carbon bearing \(-OH\).
So structure becomes:
\[ CH_3-CH(OH)-CH_3 \] which is isopropyl alcohol (2-propanol).
Final Answer: \[ \boxed{CH_3CH(OH)CH_3} \]
