Question

which is the correct answer.
C3H6O shows-
1. metamerism
2. functional isomerism
3. position isomerism
4. tautomerism​

Answer 1

Answer:

C₃H₆O shows functional group isomerism.

Explanation:

The compounds having the same molecular formula but different functional groups are called functional group isomers, and the phenomenon is called functional group isomerism. Generally, compounds having the same general formula exhibit functional isomerism. C₃H₆O is of the form CₙH₂ₙO(general formula of aldehydes, ketones and epoxides).

The following two functional isomers are possible for the molecular formula C₃H₆O.

CH₃COCH₃(propanone) and CH₃CH₂CHO(propanal)

If two or more compounds have the same functional group, but the alkyl group attached to the same functional group is different then the phenomenon is called metamerism and the compounds are called metamers.

Position isomerism arises due to a difference in the position of the substituent atom or a functional group on the carbon skeleton. Such compounds are position isomers.

Tautomerism is a phenomenon in which a single compound exists in two readily interconvertible forms, which differ markedly in the relative position of at least one atomic nucleus, generally hydrogen.

Answer 2

Solution:

$C_{3}H_{6}O$ shows function group isomer.

Explanation:

1. $C_{3}H_{6}O$ having 9 total number of structural isomers.
2. The most common organic compound with this molecular formula is propanone and propanal.
3. These two compound shows functional isomerism because one having ketone functional group and other with aldehyde functional group.
