Draw the lewis structure for the molecule ch2chch3. how many sigma and pi bonds does it 30) contain

            1-Propene has eight sigma bonds and one pi bond.

Explanation:
                   The lewis structure of 1-Propene is shown below. All sigma bonds are highlighted by blue color and the pi bond is highlighted by red color.
                   Carbon having four unpaired electrons in its excited state can form four covalent (sigma bonds) bonds. In given structure the orbitals containing unpaired electron in sp³ hybridized C undergo head to head overlap with three hydrogen atoms having single unpaired electron and orbital of other sp² hybridized carbon in same fashion. So, four sigma bonds are formed by sp³ hybridized carbon atom.
                    The doubly bonded carbon atoms also form sigma bond but two unpaired electrons of these two carbons undergo the formation of pi bond. This pi bond forms when the orbitals overlap along the plane perpendicular to the existing sigma bond resulting in the formation of single pi bond.

Lewis structure are the diagrams, which represent the bonding between atoms of a molecule. It also shows the number of lone pairs present in the atom. The propene Lewis structure shows that it has 8 sigma and 1 pi bonds.

Propene or CHCHCH, is an organic compound that is released by the burning of forest fires, motor vehicles, and aircraft exhaust. The Lewis structure of propene shows that it has 8 sigma bonds and one pi bond.

Sigma bonds are represented as single bond. Pi bonds are represented as double or triple bond.

The given image below is the Lewis structure of propene.

Carbon is a tetravalent atom, and in its its excited stated can form 4 covalent bonds. In the diagram, it is seen that carbon is hybridized. Carbon forms head to head overlapping with the three hydrogen atoms, forming three sigma bonds.

Since, the carbon is a tetravalent atom, it will form one sigma and one pi bond. The pi bonds are formed when orbitals overlap perpendicularly along the plane of sigma bond.
