The Importance of Carboxylic Acids (RCO2H) • Starting materials for acyl derivatives (esters, amides, and acid chlorides) • Abundant in nature from oxidation of aldehydes and alcohols in metabolism
10. 1 Naming Carboxylic Acids and derivatives If derived from open-chain alkanes replace the terminal -e of the alkane name with-oic acid The carboxyl carbon atom is C(1) CH. 0 CHCH.

10.1 Naming Carboxylic Acids and Derivatives • If derived from open-chain alkanes, replace the terminal -e of the alkane name with -oic acid • The carboxyl carbon atom is C(1)
Alternative names Compounds with- CO,h bonded to a ring are named using the suffix carboxvlic acid Use common names for formic acid (HCOOH) and acetic acid(CH, COOh) CO,H B 3-Bromocyclohexanecarboxylic acid 1-Cyclopentenecarboxylic acid e 2004 Thomson/Brook Coe
Alternative Names: • Compounds with ¾CO2H bonded to a ring are named using the suffix - carboxylic acid • Use common names for formic acid (HCOOH) and acetic acid (CH3COOH)
