Question

General group(s) for alcohols is/are:

• A. >C - OH
• B. >CH - OH
• C. -CH2OH
• D. all of these

Hint:

Alcohols are characterized by the -OH group, and the carbon to which it is attached can be part of different structures (e.g., -CH2OH, -C-OH).

Answer 1

The Correct Option is D

Step 1: Understanding the general structure of alcohols.
Alcohols are characterized by the presence of a hydroxyl group (-OH) attached to a carbon atom. The carbon can be part of various groups, including alkyl groups, depending on the structure of the alcohol. 
Step 2: Review the options.
- Option (A) >C - OH: Correct, this represents a general structure for alcohols, where the hydroxyl group is attached to a carbon atom. - Option (B) >CH - OH: Correct, this represents a hydroxyl group attached to a carbon atom that is also part of a larger structure. - Option (C) -CH2OH: Correct, this represents alcohols like methanol and ethanol, where the hydroxyl group is attached to a methylene group (-CH2OH). - Option (D) all of these: Correct, since all of the structures mentioned are part of alcohol functional groups. 
Final Answer: \[ \boxed{\text{all of these}} \]
