Since no choices are given, I will describe the reactivity of the element chlorine. A halogen is example of
nonmetal. When compounds containing halogens they are
called salts thus the name “salt – former”. Halogen consists of Fluorine,
Chlorine, Bromine, Iodine, Astatine. An example of is reactivity is the monochlorination of
an alkane, which involves substituting one of the hydrogen atom in the alkane and
exchange it with a chlorine atom.
CH₄ + Cl₂ → CH₃Cl + HCl
The H in methane is substituted with the
Cl in chloride.
