ISOMERISM

None

Can someone give an example in which the compond exhibits functional as well as position isomerism both ???

Please give the compond. I'll be really thankful !!!

Thanks in advance!!!

Rates assured!!!

position isomers

1-propanol CH₃CH₂CH₂OH

2-propanol CH₃CH(OH)CH₃

structural isomers

CH₃CH₂-O-CH₃

1-propanol CH₃CH₂CH₂OH

For example, consider the following examples. According to me, they exhibit both position as well as functional isomerism.

$C{H}_{3}-CH=CH-CH=CH-C{H}_{3}$

$C{H}_{3}-C{H}_{2}-CH=C=CH-C{H}_{3}$

Now, can you give me one more example of this kind.

Please help!!!

hi friend,

CH₃-CO-CH(OH)₂ methyl,methyl (gem diol) ketone (1,1 gemdihydroxy propanone )

CH₂(OH)-CO-CH₂(OH) di methyl alchohol ketone(1,3 dihydroxy propanone)

you can identify the positional isomerism... the functional difference is first one is gem diol and the second one is not gem diol...

CH₃-CH(OH)-COOH (alpha hydroxy propionic acid) is an functional isomer

Actually, gem-diol and vic-diol or any other diol - these are common names. They cannot be regarded as functional isomers.

So, the first two compounds do not exhibit functional isomerism. I'm looking for two compounds which have both osition as well as functional isomerism (in the same way the two compounds that I have given).

But you can consider alpha hydroxy propionic acid in functional isomerism. So, if we consider 1 and 3 or 2 and 3, they have functional isomerism but they do not have position isomerism.

If you want to ask anything, then you may do so!!!

Since I come online here at GOIIT for a very less time, you can nudge me. I'll see it there.

Thanks!!!
