Question

Draw the possible isomers of the compound with molecular formula \[{{\text{C}}_3}{{\text{H}}_6}{\text{O}}\] and also give their electron dot structures.

Answer 1

Hint:The above molecule contains at least 1 double bond in acyclic isomers. There is a possibility of ring chain as well as functional group isomerism.

Complete step by step answer:
Isomers are those molecules which have the same molecular formula but have different physical and chemical properties.
Stereoisomer is those isomers in which the molecules differ in the arrangement of atoms in space.
 Structural isomers are those having the same molecular formula but different properties due to different structures. They are classified as chain isomerism, position isomerism, functional group isomerism and linking isomerism.
 Functional group isomerism is that structural isomerism which has the same molecular formula but different functional group chain isomerism by that structural isomerism which has the same molecular formula but different length of principal carbon. Chain position isomerism is that structural isomerism which has the same molecular formula but different position of functional groups or multiple bond or side substituents. Ring chain isomerism is that structural isomerism which has the same molecular formula but has either the multiple bonds or ring with respect to its isomer.
There are a total of 11 isomers including stereo and structural isomers which are as:

Note:
The E and Z are known as stereo isomerism. The E isomer is when the same priority group is present on the opposite side and the Z isomer is when the same priority group is present on the same side. They should not be confused with cis and trans isomers. Cis and trans are geometrical isomer in which same groups are present on similar and opposite sides. R and S are known as stereoisomers.
