The suffix used in carboxylic acid is :

Which of the following funtional groups is common to aldehydes , ketones and carboxylic acids ?

Read the passage given below and answer the following questions: Aldehydes, ketones and carboxylic acids are few of the major classes of organic compounds containing carbonyl group. Aldehydes are prepared by dehydrogenation or controlled oxidation of primary alcohols and controlled or selective reduction of acyl halides. Ketones are prepared by oxidation of secondary alcohols and hydration of alkynes. Carboxylic acids are prepared by the oxidation of primary alcohols, aldehydes and alkenes by hydrolysis of nitriles and by treatment of Grignard reagents with carbon dioxide. Name a method by which both aldehydes and ketones can be prepared.

Through which of the following reactions number of carbon atoms can be increased in the chain?

Ketones can NOT be converted into carboxylic acid using____.

Aldehydes and ketones undergo nucleophilic addition reactions. With weak nucleophiles such as ammonia and its derivatives, (H_2 N-Z) , aldehydes and ketones react in weakly acidic medium to form compounds containing carbonnitrogen double bond with the elimination of water to form . Aldehydes can be easily oxidised to carboxylic acid on treatment with common oxidising agents like KMnO_4 K_2 Cr_2 O_7 , HNO_3 , etc. The carboxylic acid formed contain the same number of carbon atoms as the aldehydes. However ketones under drastic conditions with powerful oxidising agents undergo cleavage of C-C bond giving mixture of carboxylic acids having lesser number of C atoms than the original ketone. Write the reaction of acetone with semicarbazide.
