Question

Name the first member of the Ketone family, write its molecular formula, electron dot structure, and IUPAC name.

Answer 1

Ketone:

• In a Ketone, there are two Carbon groups attached to the Carbonyl carbon atom.
• The general formula for ketone can be shown as :

• Here, R represents an Alkyl group whereas Ar stands for an Aryl group.
• The common name for Ketones can be determined by naming the Alkyl groups attached to the Carbonyl and then adding ‘Ketone’ with it i.e Methyl ketone, Ethyl ketone.
• Many ketones are of great importance in industry and in biology.

The first member of the Ketone family:

• The first member of the ketone family is known as Acetone or Propanone.
• The Molecular formula for this can be given as: ${\mathrm{C}}_3{\mathrm{H}}_6\mathrm{O}\mathrm{or}{\mathrm{CH}}_3-\mathrm{CO}-{\mathrm{CH}}_3\mathrm{or}{\left({\mathrm{CH}}_3\right)}_2\mathrm{CO}$ .
• IUPAC Name of the compound is Propan-2-one.
• The electron dot structure of Acetone can be shown as :

Hence, the above given are the respective details of the first member of the ketone family i.e Acetone .
