Question

Propanone and $ {\text{Prop - 2 - en - 1 - ol}} $ are which type of isomerism?

Answer 1

Hint: Let us first understand that isomerism is a phenomenon. And in this phenomenon, two or more chemical compounds have the same molecular formula. Isomerism arises from the fact that the atoms in a molecular formula can be organized in multiple ways to produce compounds with varied physical and chemical properties, known as isomers. Isomerism can be classified into two types: structural isomerism and stereoisomerism, which can be further subdivided.

Complete Step By Step Answer:
Propanone and $ {\text{Prop - 2 - en - 1 - ol}} $ belong to the type of isomerism called functional isomerism.
Functional isomers are referred to those two or more compounds with the same chemical formula but distinct functional groups. This particular phenomenon is known as functional group isomerism. The same sets of atoms are rearranged in such a way that the two functional isomers have considerably different attributes due to the presence of different functional groups.
Propanone and $ {\text{Prop - 2 - en - 1 - ol}} $ satisfies the above conditions and thus they are functional isomers.

Additional Information:
-Skeletal isomerism is another name for chain isomerism. These isomers' constituents have different branching structures.
-Position isomers differ in the positions of functional groups or substituent atoms.
-The presence of distinct alkyl chains on each side of the functional group causes metamerism.

Note:
It can be noted that structural isomerism can be further divided into chain isomerism, metamerism, functional isomerism, tautomerism, positional isomerism, and ring-chain isomerism. Geometric and optical isomerism comes under stereoisomerism. The term that is used to describe structural isomerism is constitutional isomerism. The functional groups and atoms in these isomers' molecules are linked in different ways.
