Chapter 16: Q2P (page 742)

Why are numbers not used to designate the position of the functional group in propanone and butanedione?

Short Answer

Expert verified

If the position of carbonyl group changes, then it would not be considered as a ketone.

Step by step solution

01

Step-by-step-solutionStep 1: Ketones

Ketones come under the category of carbonyl compounds. The IUPAC name of the ketones is acquired by replacing ‘e’ on the end of the parent hydrocarbon with “one”. Some examples of ketone are 2-propanone and 2-methyl-2-butanone.

Reason for not using numbers to designate the position of functional groups in propanone and butanedione

The structure of propanone and butanedione can be given as:

Structure of the compounds

The numbers are not used to designate the functional group position in propanone and butanedione as if the position of the carbonyl group changes, then that compound will not be a ketone.
