Question

preparation of alkanes from carboxylic acids​

Answer 1

Answer:

Preparation of alkanes from carboxylic acids:

Preparation of alkanes from carboxylic acids mainly happens via two means:

Alkanes can be prepared from carboxylic acid via the removal of carbon dioxide. This process is known as decarboxylation. It produces alkane with a carbon atom lesser than that present in the carboxylic acid.

Kolbe’s electrolytic method: In this process, the alkane is produced through electrolysis of sodium or potassium salt of carboxylic acid.

Answer 2

Answer:

Explanation:

REACT THE CARBOXYLIC ACID WITH BASE

TO FORM CARBOXYLIC SALTS

SUPPOSE WE HAVE METHYL CHLORIDE

CH3CL = CH3+ +CL-

SUPPOSE WE HAVE CH3COONA CARBOXYLIC SALT

FIRST BREAK CARBOXYLIC SALT

CH3COO- AND NA+

AND TAKE HOMOLYTIC FISSION FROM CH3COO-

CH3. AND CO2- ARE FORMED

REACT THIS CH3. WITH CH3. TO FORM ETHANE

REACT NA+ WITH CL-

NACL

SO PRODUCTS ARE ETHANE , CO2 AND NACL

THIS IS THE PROCESS OF PREPARATION OF ALKANES FROM CARBOXYLIC ACIDS
