Question

Write the industrial name and two uses of ethyne.

Answer 1

Hint: Ethyne is the IUPAC name of a hydrocarbon that comes from the family of alkyne. In this name the prefix is eth and the suffix is -yne. Eth is used because of two carbon atoms and -yne is used because there is a triple bond between carbon-carbon atoms. It is an unsaturated hydrocarbon.

Complete answer:
In this question, we have to tell the industrial name of ethyne and its uses. An industrial name is a name that is used commonly. It is the common name of the compound. The common name of ethyne is acetylene. The molecular formula of this compound is ${C_2}{H_2}$. It is the simplest alkyne. It is unstable in the pure form so it is used as a solution. Pure acetylene is odorless but commercial used has some odor to some impurities.
Uses of acetylene: It is used in preparation of substances such as ethanol, acetic acid, vinyl chloride, and plastic. It is used in an oxyacetylene flame which is used in welding. It is used in the production of portable lighting as well. Calcium carbide was used to generate acetylene used in lamps for portable or remote applications such as mining. Acetylene is prepared by the reaction of calcium carbide with water. This reaction is written below:
$Ca{C_2} + 2{H_2}O\xrightarrow{{}}Ca{\left( {OH} \right)_2} + {C_2}{H_2}$


Note:
Polymerization of acetylene with Ziegler-Natta catalysts produces polyacetylene films. Ziegler-Natta catalyst is used in the synthesis of $1 - $ alkenes. Polyacetylene refers to an organic polymer with ${\left( {{C_2}{H_2}} \right)_n}$ as repeating units.
