Answer : The Lewis-dot structure of [tex]C_3H_4[/tex] is shown below.
The number of sigma and pi-bonds are 6 and 2 respectively.
Explanation :
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
In the Lewis-dot structure the valance electrons are shown by 'dot'.
The given molecule is, [tex]C_3H_4[/tex]
As we know that carbon has '4' valence electrons and hydrogen has '1' valence electron.
Therefore, the total number of valence electrons in [tex]C_3H_4[/tex] = 3(4) + 4(1) = 16
According to Lewis-dot structure, there are 16 number of bonding electrons and 0 number of non-bonding electrons.
The number of sigma and pi-bonds are 6 and 2 respectively.
