For preparing an alkane, a saturated solution of sodium or potassium salt of a carboxylic acid is subjected to

A

hydrolysis

B

oxidation

C

hydrogenation

D

electrolyis

Text Solution

Verified by Experts

The correct Answer is:
D
When an concentrated aqueous solution of the sodium or potassium salt of a monocarboxylic acid is electrolysed, an alkane is produced as shown below
`underset("sod. ethanoate")(2CH_(3)COONa) + 2H_(2)O overset("Electrolysis")(rarr) underset("ethane")(CH_(3) - CH_(3)) + 2NaOH + H_(2) + 2CO_(2)`
