CHCl3 is called chloroform. First we need to count the total number of valence electrons. We just add the valence electrons of each atoms involved.

C = 4

Cl = 7 x 3

H = 1

------------

    26 electrons

Next, we have to assign the central atom; In this case it is C.

Now we have to connect the atoms and form bonds. We can form three C-Cl bonds and one C-H bonds.

          H

          |

   Cl - C - Cl

          |

         Cl

Finally, we have to distribute the remaining electrons on C atoms provided that it follow the octet rule. 

            H

      ..    |    ..

   : Cl - C - Cl :

      ''    |     ''

         : Cl :

CHCl3 is similar with Metane (CH4) in terms of geometry. CHCl3 is a tetrahedral molecule therefore it has a bond angle of 109.5 degrees. and it is polar
