Question

Define functional group isomerism

Answer 1

Functional isomerism, an example of structural isomerism, occurs substances have the same molecular formula but different functional groups.

This means that functional isomers belong to different homologous series. ...

There are two functional group isomers of which you need to be aware: alcohols and ethers.

i guess it will help you

Answer 2

hi slmn....

functional group isomerism.....

in this variety of structural isomerism, the isomers contain different functional groups - that is, they belong to different families of compounds (different homologous series).

For example, a molecular formula C3H6O could be either propanal (an aldehyde) or propanone (a ketone).

There are other possibilities as well for this same molecular formula - for example, you could have a carbon-carbon double bond (an alkene) and an -OH group (an alcohol) in the same molecule.

Another common example is illustrated by the molecular formula C3H6O2. Amongst the several structural isomers of this are propanoic acid (a carboxylic acid) and methyl ethanoate (an ester).

hope i answered your question....
