An aldehyde as well as a ketone can be represented by the same molecular formula, say `C_(3)H_(6)O`. Write their structures and name them. State the relation between the two in the Language of science.

Explanation

Molecular formula: `C_(3)H_(6)O`
`"Aldehyde": H-underset(H)underset(|)overset(H)overset(|)C-underset(H)underset(|)overset(H)overset(|)C-overset(H)overset(|)C = O" "or" "CH_(3)-CH_(2)-CHO` , Propanal
`"Ketone": H-underset(H)underset(|)overset(H)overset(|)C-underset(O)underset(||)C-underset(H)underset(|)overset(H)overset(|)C -H" "or" "CH_(3)-underset(O)underset(||)C-CH_(3)` , Propanone
They are called isomers because both have same molecular formula but different structural formula (having different functional groups). They do not have same physical properties since their functional group is different.
