Electron dot structure of propanone class 10

Propanone is an organic compound having a Ketone group. Today we will discuss how to draw electron dot structure of propanone.


Propanone is also called Acetone.


We will discuss the electron dot structure of propanone  through the following points

 

 

   1.   Formula of propanone

   2.   Electronic configuration of carbon

   3.   Electronic configuration of hydrogen

   4.   Electronic configuration of oxygen

   5.   Find the central atom in the compound

   6.   Draw the structural formula of propanone

   7.   Electron dot structure of propanone


Formula of Propanone


`CH_3COCH_3`  or `C_3H_6O`


Electronic configuration of carbon


`1s^2 2s^2 2p^2`

Carbon has four valence electrons in the outermost shell.


Electronic configuration of hydrogen


`1s^1`

Hydrogen has one valence electron in the outermost shell.


Electronic configuration of oxygen


`1s^2 2s^2 2p^4`

Oxygen has 6 valence electrons in the outermost shell.


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.
