Lewis Structures for Various Compounds

a) Chlorine (Cl₂)

Chlorine (Cl₂) consists of two chlorine atoms sharing one pair of electrons. Each chlorine atom has seven valence electrons, and they share one electron to form a single bond, completing their octet.

Cl : Cl

b) Hydrogen Iodide (HI)

Hydrogen Iodide (HI) is composed of one hydrogen atom and one iodine atom. Hydrogen has one valence electron, and iodine has seven. They share one electron to form a single bond, with iodine completing its octet.

H : I

c) Chloroform (CHCl₃)

Chloroform (CHCl₃) has one carbon atom, one hydrogen atom, and three chlorine atoms. Carbon shares one electron with hydrogen and one electron with each chlorine atom, forming four single bonds. Carbon completes its octet, and each chlorine atom also completes its octet.
