Answer : The Lewis-dot structure of [tex]^-CH_2CN[/tex] is shown below.
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]^-CH_2CN[/tex]
As we know that carbon has '4' valence electrons, hydrogen has '1' valence electron and nitrogen has '5' valence electrons.
Therefore, the total number of valence electrons in [tex]^-CH_2CN[/tex] = 4 + 2(1) + 4 + 5 + 1 = 16
According to Lewis-dot structure, there are 12 number of bonding electrons and 4 number of non-bonding electrons.
In this molecule, (CN) is cyanide group in which carbon bonded to the nitrogen by triple bond.
Hence, the Lewis-dot structure of [tex]^-CH_2CN[/tex] is shown below.
