The correct IUPAC name of the compound given below is :

• A. $\text{5-carbamoylcycloheptanecaboxylic acid}$
  
• B. $\text{4-ethanoylaminocycloheptanecarboxylic acid}$
• C. $\text{4-carbamoylcycloheptanecaboxylic acid}$
  
• D. $\text{6-carbamoylcyclooctanoic acid}$

Answer 1

The correct option is B $\text{4-ethanoylaminocycloheptanecarboxylic acid}$

Amides $(-CON{H}_2,-CONHR,-CON{R}_2)$
Suffix: −amide/carboxamide
Prefix: ethanoyl amino is used in case of $-NHCOC{H}_3$.

Here, in the compound at 4th position of the parent ring, $-NHCOC{H}_3$ is present. So, ethanoyl amino prefix should be used.


Therefore the correct IUPAC name of the following compound is$\text{4-ethanoylaminocycloheptanecarboxylic acid}$
