Class 12 Chemistry Aldehydes Ketones Acids Preparation of only ketones

Preparation of only ketones

1.From acyl chloride :  In this we make use of dialkyl cadmium ,then we react with RCOCL. For preparation we take grignard reagent :

Lets prepare acetophenone by this method :

 2.From nitriles : In this we make use of grignard reagent and nitriles as shown in reaction :

In a similar manner, we can prepare acetophenone by taking grignard reagent as phenyl magnesium bromide and methyl cyanide.
