Carboxylic Acid Reactivity

Sodium borohydride NaBH 4 does not reduce carboxylic acids however hydrogen gas is liberated and salts of the acid are formed Partial reduction of carboxylic acids directly to aldehydes is not possible but such conversions have been achieved in two steps by way of certain carboxyl derivatives These will be described later 2 Oxidation

Carboxylic acid

Carboxylic acid - Carboxylic acid - Synthesis of carboxylic acids: Most of the methods for the synthesis of carboxylic acids can be put into one of two categories: (1) hydrolysis of acid derivatives and (2) oxidation of various compounds All acid derivatives can be hydrolyzed (cleaved by water) to yield carboxylic acids the conditions required range from mild to severe depending on the

Ch19: Carboxylic Acids

Carboxylic acids (RCO 2 H) are a common and important functional group (e g amino acids fatty acids etc ) and provide the point of access to the carboxylic acids derivatives (acyl chlorides acid anhydrides esters amides etc ) Carboxylic acids are the most acidic of the common organic functional groups

Oxidation of Alcohols

The rate of oxidation varies between primary secondary and tertiary alcohol On the basis of their oxidation rates alcohols can be distinguished as: Primary alcohol gets easily oxidized to an aldehyde and can further be oxidized to carboxylic acids too Secondary alcohol gets easily oxidized to ketone but further oxidation is not possible
