I’m super excited to teach you the lewis structure of C3H6 in just 3 simple steps.
Infact, I’ve also given the step-by-step images for drawing the lewis dot structure of C3H6 molecule.
So, if you are ready to go with these 3 simple steps, then let’s dive right into it!
Lewis structure of C3H6 (or Propene) contains one C-C bond, one C=C bond, and six C-H bonds. The three Carbon atoms (C) are at the center and they are surrounded by six Hydrogen atoms (H).
Let’s draw and understand this lewis dot structure in simple steps.
3 Steps to Draw the Lewis Structure of C3H6 (Propene)
Step #1: Calculate the total number of valence electrons
Here, the given molecule is C3H6 (also known as Propene). In order to draw the lewis structure of C3H6, first of all you have to find the total number of valence electrons present in the C3H6 molecule.
(Valence electrons are the number of electrons present in the outermost shell of an atom).
So, let’s calculate this first.
- For Carbon:
Carbon is a group 14 element on the periodic table.
Hence, the valence electrons present in carbon is 4 (see below image).
- For Hydrogen:
Hydrogen is a group 1 element on the periodic table.
Hence, the valence electron present in hydrogen is 1 (see below image).
Hence in a C3H6 molecule,
Valence electrons given by each Carbon (C) atom = 4
Valence electron given by each Hydrogen (H) atom = 1
So, total number of Valence electrons in C3H6 = 4(3) + 1(6) = 18
Step #2: Make the rough sketch
C3H6 (propene) is an alkene that has 3 carbon atoms in a row along with one double bond between the two carbon atoms. And the rest of the other bonds are single bonds.
All the three carbon atoms are surrounded by hydrogen atoms.
The above sketch contains 9 pairs of electrons, that means we have used all the 18 valence electrons.
Step #3: Check the stability of all the atoms
In the Lewis structure of C3H6, the outer atoms are hydrogen atoms. These hydrogen atoms form a duplet and hence they are stable.
Also you can see that the three central carbon atoms are forming an octet. Hence the carbon atoms are also stable.
You can see in the above image that all the hydrogen atoms as well as carbon atoms are stable.
And hence, the above lewis dot structure of C3H6 (i.e propene) is the final stable structure only.
Each electron pair (:) in the lewis dot structure of C3H6 represents the single bond ( | ). So the above lewis dot structure of C3H6 can also be represented as shown below.
