There are three cyclic isomers possible for the formula C3H6O: two variations of oxirane and one of cyclopropanol. There are two acyclic isomers: propanal and 2-propanol.
Compounds that have different connectivity of atoms but the same molecular formula are called constitutional isomers. For example, butane and isobutane are constitutional isomers since they have the same molecular formula (C4H10) but different structures. Other examples include pentane and neopentane, as well as ethanol and dimethyl ether.
There are five constitutional isomers for C3H7. They are propane, methylpropane (isobutane), dimethylmethane (neopentane), ethylmethyl (butane), and trimethylmethane (isopentane).
Ethanol and dimethyl ether: Constitutional isomers. 1-chloropropane and 2-chloropropane: Constitutional isomers. Cis-2-butene and trans-2-butene: Stereoisomers.
C3H4O can have two isomers: propynal and cyclopropanone.

Compounds that have the same atoms (molecular formula) but different in the connectivity between the atoms are constitutional (formerly 'structural') isomers.
C3H4O can have two isomers: propynal and cyclopropanone.
The constitutional isomers of hexane (C6H14) are: n-hexane (normal hexane) 2-methylpentane 3-methylpentane
The simplest alkane capable of having constitutional isomers is propane (C3H8).
The isomers of C5H11Cl include n-pentyl chloride, isopentyl chloride (or 2-methylbutyl chloride), and neopentyl chloride (or 2,2-dimethylpropyl chloride).
The isomers of 1-hexyne are cis-2-hexene, trans-2-hexene, and 3-hexyne. These isomers have different chemical structures due to the positioning of the carbon-carbon triple bond within the hexane chain.
