Question

What is the IUPAC name of CH3CH(CH3)CH2COOH?

a) 2-Methylbutanoic acid
b) 3-Methylpentanoic acid
c) 2-Ethylbutanoic acid
d) 4-Methylhexanoic acid

Answer 1

The IUPAC name of the compound
`CH_3CH(CH_3)CH_2COOH`is 2-Methylbutanoic acid, and this corresponds to option (a).

Step-by-step explanation:

The compound
`CH_3CH(CH_3)CH_2COOH` is an organic molecule with a carboxylic acid functional group. To name this compound using IUPAC conventions, we must first identify the longest continuous carbon chain that includes the carboxylic acid. This chain is butane, with four carbon atoms. Next, we investigate any alkyl substitutions on this chain. There is a methyl group (
`CH_3`) attached to the second carbon atom of the butane chain.

Therefore, incorporating these findings, we can determine that the IUPAC name for this molecule is 2-Methylbutanoic acid, which corresponds to option (a). This systematic naming approach ensures a precise and standardized way to identify organic compounds, facilitating clear communication among chemists and researchers regarding the structure and properties of the molecules involved.
