How butane is formed from but-2-yne .explain with example?
Answers
Explanation:
The given conversion is of butane to but-2-yne. The conversion of butane to but-2-yne occurs in four steps, which are stated below.
1. In the first step, the treatment of butane occurs with bromine gas under the action of UV light. This is known as single radical halogenation of butane and results in the formation of 2-bromobutane. The reaction is shown below.
2. In the second step, 2-bromobutane reacts with alcoholic potassium hydroxide to form but-2-ene. The reaction is shown below.
3. In the third step, the reaction of but-2-ene occurs with bromine gas under the action of C C l 4 that results in the formation of 2, 3-dibromobutane. The reaction is shown below.
4. In the final step, 2, 3-dibromobutane undergoes reaction with Na N H 2 in the presence of liquid ammonia to form but-2-yne, the final product. The reaction is shown below.
