Question

Propanone and prop-2-en-1-ol are examples of which type of isomerism?

Answer 1

Isomerism:

• The compounds having the same molecular formula, which differ in at least some physical or chemical properties, are known as isomers and the phenomenon is said to be isomerism.
• The different types of isomerism are chain isomerism, position isomerism, and functional isomerism.
• The chain isomerism is due to the arrangement of carbon atoms so the size of the parent chain or the size of the side chain must be different.
• The position isomerism is due to different locant numbers of functional groups or multiple bonds or side chains along the same parent chain.
• Functional isomerism is due to the presence of different functional groups.

Propanone and Prop-2-en-1-ol:

• Propanone is an organic compound that contains three Carbon atoms and one ketone group.
• The molecular formula of Propanone is ${\mathrm{C}}_3{\mathrm{H}}_6\mathrm{O}$.
• The structural formula of Propanone is,

• Prop-2-en-1-ol is an organic compound that contains three Carbon atoms and one alcohol group.
• The molecular formula of Prop-2-en-1-ol is ${\mathrm{C}}_3{\mathrm{H}}_6\mathrm{O}$
• The structural formula of Prop-2-en-1-ol is ${\mathrm{CH}}_2=\mathrm{CH}-{\mathrm{CH}}_2-\mathrm{OH}$
• That is, both Propanone and prop-2-en-1-ol are having same molecular formula but different structural formulas.
• Both Propanone and prop-2-en-1-ol contain different functional groups, that is they are functional isomers.

Therefore, Propanone and prop-2-en-1-ol are examples of functional isomers.
