Draw the possible isomers of the compound with molecular formula $C_3H_6O$ and also give their electron dot structures.

(N/A) The molecular formula $C_3H_6O$ corresponds to two functional isomers:
$1$. Propanone $(CH_3COCH_3)$: $A$ ketone.
$2$. Propanal $(CH_3CH_2CHO)$: An aldehyde.
The electron dot structures are as follows:
- For Propanone: The central carbon atom is double-bonded to an oxygen atom and single-bonded to two methyl groups.
- For Propanal: The terminal carbon atom is double-bonded to an oxygen atom and single-bonded to a hydrogen atom and an ethyl group.
