Question

The molecular formula of chlorine is $C{l_4}$
A. True
B. False

Answer 1

b>Hint: Chlorine is a chemical element with the symbol $Cl$ and atomic number 17. It is the second lightest element of the halogens, and it appears between fluorine and bromine in the periodic table. It is yellow-green gas at room temperature.

Complete step by step answer:
Chlorine is a green yellow gas with a very pungent odor that is twice as dense as air. It is basically a chemical element that belongs to the halogen group with the symbol $Cl$. It was discovered in 1770 and soon became useful as a commercial agent.
The molecular formula of this gas is $C{l_2}$ and it is a diatomic molecule which means that it has two atoms of the same element in the molecule. Its structure is as shown:

Moreover, chlorine reacts with organic compounds and ammonia to form chloro-organics or chloramines. These are the part of the group of chlorine compounds that have disinfectant properties and show up as part of chlorine.
It also acts as a reducing agent present in wastewater. These reactions are called chlorine demand. The reaction is as shown:
${H_2}O + C{l_2} \to HCl + HClO$
Therefore, in the given question the molecular formula of chlorine is wrong.

Hence, it is false. Option B is correct.

Note: Chlorine gas was used by the Germans as a chemical weapon against the allied troops during the First World War. It is an intermediate water-soluble pulmonary irritant that causes acute damage in the upper and lower respiratory tract. Furthermore, it is also used to prevent the spread of various waterborne diseases.
