Explain the Wolff-Kischner reduction of acetone and write the equation for the same. 

Explanation

The reduction of aldehydes and ketones into corresponding hydrocarbons by heating with a mixture of hydrazine and strong base like KOH in ethylene glycol is called wolff kishner reduction.

When acetone is reacted with hydrazine gives Acetone hydrazone which is treated KOH ethylene glycol and heating gives propane.
