The functional group present in propanone isA Carboxy B Ketonic C Aldehydic D Alcoholic

Break Down the Problem

1. Identify the compound "propanone."
2. Determine the functional groups associated with the options provided.

Relevant Concepts

1. The structure of propanone (also known as acetone) is CH₃COCH₃.
2. Understand the definitions of different functional groups:
   • A: Carboxy groups (RCOOH)
   • B: Ketonic groups (RC(=O)R')
   • C: Aldehydic groups (RCHO)
   • D: Alcoholic groups (R-OH)

Analysis and Detail

1. Propanone has the functional group where a carbonyl (C=O) is bonded to two carbon atoms, making it a ketone.
2. Compare propanone to the definitions:
   • It does not have a carboxy group (Answer A is incorrect).
   • It fits the ketonic group criteria (Answer B is correct).
   • It lacks an aldehyde group (Answer C is incorrect).
   • It is not an alcoholic compound (Answer D is incorrect).

Verify and Summarize

1. Propanone is identified as having a carbonyl group situated between two other carbon atoms.
2. The functional group analysis confirms that the only accurate representation is the ketone.

Final Answer

B: Ketonic
