Find the central atom in the compound
Propanone has three carbon atoms including -CO- group.
Carbon atoms form the main chain of the compound.
Structural formula of Propanone
The carbon atom requires four electrons to complete its
octet and hydrogen atom requires one more electron to attain stable noble gas
configuration and the oxygen atom requires two electrons.
Two carbon atoms other than -CO- group share 1-1
electron with hydrogen atoms and carbon.
In the -CO- group, carbon and oxygen atoms share 2-2 electrons forming a double bond.
