Question

question
identify the name of the carboxylic acid derived from an alkane with one carbon.
select the correct answer below:
o methanoic acid
o monocarboxylic acid
o monoalkane acid
o ethanoic acid

Explanation:

Step1: Analyze alkane with one carbon

The alkane with one carbon is methane (\(CH_4\)).

Step2: Determine carboxylic acid naming rule

Carboxylic acids are named by replacing the -e of the corresponding alkane with -oic acid.

Step3: Name the carboxylic acid

For methane (\(CH_4\)), replacing -e with -oic acid gives methanoic acid (\(HCOOH\)).
Mono - carboxylic acid is a general term for carboxylic acids with one -COOH group. Mono - alkane acid is not a standard name. Ethanoic acid (\(CH_3COOH\)) is derived from ethane (\(C_2H_6\)) which has two carbon atoms.

Answer:

A. methanoic acid
