1 butyne is converted to 2 butyne by usinga)NaNH2b)Alc. KOHc)C2H5ONad)...
Alc. KOH
Alc. KOH stands for alcoholic potassium hydroxide, which is commonly used in organic chemistry reactions. In this case, 1-butyne is converted to 2-butyne by using alcoholic KOH.
Reaction Mechanism
- The reaction involves the deprotonation of 1-butyne by alcoholic KOH, leading to the formation of a potassium acetylide intermediate.
- The acetylide ion then undergoes protonation by another molecule of 1-butyne to form 2-butyne.
Role of Alcoholic KOH
- Alcoholic KOH acts as a base in this reaction, facilitating the deprotonation of the terminal alkyne.
- It also helps in the formation of the potassium acetylide intermediate, which is crucial for the conversion of 1-butyne to 2-butyne.
Advantages of Using Alc. KOH
- Alcoholic KOH is a strong base, making it effective in deprotonating the terminal alkyne.
- It is relatively easy to handle and is commonly used in organic synthesis.
Conclusion
By using alcoholic KOH in the reaction, 1-butyne can be efficiently converted to 2-butyne through a series of protonation and deprotonation steps. This reaction is a common method in organic chemistry for modifying alkynes.
