Do note that "n" is NOT the "number of carbon atoms" for Carboxylic Acids. Instead, "n" = number of carbon atoms - 1. Try it our for the different members of Carboxylic Acids Homologous Series and you will understand what i mean. Hope this information helps. PS: Good question - this is one of the common misconceptions by chemistry students! Hi pinacolada,

General Molecular Formula of Carboxylic Acids are CnH2n+1COOH.

Do note that “n” is NOT the “number of carbon atoms” for Carboxylic Acids.

Instead, “n” = number of carbon atoms – 1.

Try it our for the different members of Carboxylic Acids Homologous Series and you will understand what i mean.

Hope this information helps.

PS: Good question – this is one of the common misconceptions by chemistry students!
