The electron dot structure for a compound with the formula CHClO would consist of carbon as the central atom bonded to hydrogen, chloride and oxygen. There are two lone pairs of electrons on oxygen and three lone pairs of electrons on chloride that do not share bonds with other atoms.
Electron dot structures, also known as Lewis structures, represent the bonds that take place between atoms and any electron pairs that are left that do not participate in bonding. A pair of "dots" represents an unpaired set of two electrons. Single bonds are represented by one line, while double bonds are represented by two lines.
