Question

Define the term isomers. (ii) draw two possible isomers of compound with molecular formula c3h6o and write their names.

Answer 1

Compounds having same molecular formula but different molecular structures are known as structural isomers.

Answer 2

Answer: Isomers are the compounds which have same molecular formula but different structural formula.

The possible isomers for $C_3H_6O$ are $CH_3CH_2CHO$ and $CH_3COCH_3$

these are called as functional isomers as they have same molecular formula but different functional groups.

IUPAC name of $CH_3CH_2CHO$ is propanal as it conatins aldehyde (-CHO) as the functional group and IUPAC name of $CH_3COCH_3$ is propanone a it contains (-C=O) as the functional group.
