Question

What is the correct IUPAC name of the compound given below?

• A. $\text{4-(propoxycarbonyl)cyclohexanecarboxylic acid}$
• B. $\text{4-(butoxycarbonyl)cyclohexanecarboxylic acid}$
  
• C. $\text{6-(propoxyloxy)cyclohexanecarboxylic acid}$
• D. $\text{4-(butanoyloxy)cyclohexanecarboxylic acid}$

Answer 1

The correct option is A $\text{4-(propoxycarbonyl)cyclohexanecarboxylic acid}$

Carboxylic acids $(-COOH)$
Suffix: −oic acid/carboxylic acid.
Prefix: carboxy

Esters $(-COOR)$ :
Suffix: −oate/carboxylate
Prefix: alkoxy carbonyl is used when $-C=O$ of ester is directly attached to parent chain.
Here cyclohexane is the parent chain and at 4th position , ester group is present as a substituent. So, prefix alkoxy carbonyl is used.
The correct IUPAC name of the following compound is
$\text{4-(propoxycarbonyl)cyclohexanecarboxylic acid}.$
