Which of the following methods is used to prepare ethyne on the industrial scale?
Correct answer: D. Reaction of calcium carbide with water
- A. Dehydrohalogenation of vic-dihalides
- B. Dehalogenation of tetrahalides
- C. Electrolysis of aqueous solution of potassium salt of unsaturated dicarboxylic acids
- D. Reaction of calcium carbide with water
Explanation
On an industrial scale, ethyne (acetylene) is prepared by reacting calcium carbide with water, which produces ethyne and calcium hydroxide.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.

The ozonolysis of an olefin gives propanone (acetone). The olefin is:
An alkylhalide (RCI) reacts with Li in ether medium to form RLi, which in turn reacts with H2O to 2-methylbutane. The halide (RCl) also reacts with Na in ether to form 2,7 dimethyloctane. The structure of the alkylhalide is:
