Carbon, Oxygen and Chlorine all have eight valence electrons while hydrogen has two valence electrons.
The term Lewis structure refers to the structure of a molecule in which valence electrons are shown as dots and sometimes a dash is used to show bonding between two atoms.
In the molecule CHOCl, we have the Lewis structure as shown in the image attached to this answer. Carbon, Oxygen and Chlorine all have eight valence electrons while hydrogen has two valence electrons. Therefore, all the atoms in the molecue obey the octet rule.
