Question

Westron is the solvent obtained by the reaction chlorine with:
A. Ethylene
B. Ethyne
C. Ethane
D. Methane

Answer 1

Hint: To answer this question, we should know about westron. The answer to this question is colourless gas. Mixtures of air and this product is very explosive. The answer of this question is to possess explosive and fire hazard.

Step by step answer:
Westron has the IUPAC name of 1,1,2,2 tetrachloroethane. We should know that westron has the chemical formula of ${C_2}{H_2}{Cl_4}$. We also know it by the name of acetylene tetrachloride and is a member of chloroethane.
Now, we will know by the preparation of westron. Westron is prepared from acetylene or ethyne. We should know that westron is prepared from chlorination of ethyne. The reaction to convert ethyne to westron is as follows:

Full reaction of this conversion is as follows:
\[CH\equiv CH+C{{l}_{2}}\xrightarrow{CC{{l}_{4}}}CHCl=CHCl\xrightarrow{CCl4}CHCl2-CHCl2~\left( westron \right)\]

So, from the above reaction we can say that ethyne present in option B is correct. Now, we know that westron is produced by reaction of chlorine with ethyne.

Note: We should know that westron is a pale yellow liquid. And we should know that it has sweet odour. Westron is heavy and non-flammable liquid. As it is a heavy liquid, when we dissolve in water it sinks into it. We should know that it is toxic in nature. We should know that when we do chlorination of westron, all the hydrogen atoms are replaced by chlorine. The product is called hexachloroethane.
We should not confuse westron to westrol. Trichloroethylene (\[CHClCC{{l}_{2}}\]) is called westrol.
