Question

How to prepare an alkane or a cycloalkane from hexanedioic acid??

Answer 1

An alkane is a simple organic compound that consists of only hydrogen and carbon bonded with only single bonds between carbon atoms. Alkanes are of three types: linear, branched and cycloalkanes.

Cycloalkanes are alkanes in which the carbon atoms join to form a ring.

Hexanedioic acid is a dicarboxylic acid, also called Adipic acid.

Sodium or potassium salt of a dicarboxylic acid during electrolysis gives an alkene. An alkene is generated when an aqueous solution of sodium or potassium salt of a dibasic acid (with adjacent carboyxlic groups) is electrolyzed.

Formula: 2H2O+2e−→2OH−+H2(g)

Answer 2

Dear student,

● Answer -
Hexanedioic acid on electrolysis by Kolbe reaction gives cyclobutane.

● Explaination -
Hexanedioic acid is shown by formula HOOC-(CH2)4-COOH.

Hexanedioic acid on electrolysis by Kolbe reaction gives cyclobutane.


At anode -
-OOC-(CH2)4-COO- --> C4H8 + 2CO2 + 2e-

At cathode -
2H+ + 2e- --> H2

* The reaction involves decarboxylation of dicarboxylic acid to form cycloalkane.

Hope this helped...
