Question

Are these two examples of functional isomerism?

Answer 1

Hint: Functional isomerism is the type of isomerism in which the compounds that have the same molecular formula, but have different functional groups. First check the compound if they have the same molecular formula, then check them for functional isomerism.

Complete step by step answer:
First, let us count the number of Carbon, Hydrogen and Oxygen to see if its molecular formula is the same.
As we can see, both compounds have 3 carbons, 6 hydrogen and 2 oxygen. Therefore, its molecular formula is the same, i.e. \[{{C}_{3}}{{H}_{6}}{{O}_{2}}\].
Now let us check both the compounds for functional isomerism.
Compound 1

This compound is an epoxy alcohol

Name – 1,2-epoxy propanol

Compound 2
                                      

                              This compound is an ester
                              Name – methyl acetate or methyl ethanoate

Since, the functional groups in both the compounds are different
Therefore, the answer is – Yes, the given compounds are functional isomers.

Additional Information:
While deciding the kind of structural isomerism, follow the priority order –
Ring Chain isomerism (consider it at priority)
Tautomerism
Functional isomerism
Metamerism
Chain isomerism
Position isomerism

Note: Stereoisomerism is another kind of isomerism, which is further divided into conformational and configurational isomerism. This kind of isomerism deals with the spatial arrangement or orientation of molecules atoms in a compound in space.
