Answer:
The lewis structure is shown in the figure.
Explanation:
In order to write lewis structure we will fist count the total valence electrons in the molecule.
Valence electrons of carbon = 4
Valence electrons of chlorine = 7x3 = 21
Valence electrons of hydrogen = 1
total = 26
Let us give two electrons between carbon and each of chlorine
Also give two electrons between carbon and hydrogen
total electrons left = 26-8 = 18
These eighteen electrons will be distributed over three chlorine atoms as lone pair of electrons (three pairs on each chlorine).
Thus the structure will be as shown in image.
