(a)
Interpretation:
The structure and the name of the product formed from the reaction between methyl sodium acetylide and ethyl iodide is to be stated.
Concept introduction:
Alkylenic anions are stronger bases. They can easily donate electrons due to the presence of
(b)
Interpretation:
The structure and the name of the product formed from the reaction between butyl tosylate and phenyl sodium is to be stated.
Concept introduction:
Alkylenic anions are stronger bases. They can easily donate electrons due to the presence of bonds and the negative charge. They react with alkyl halides or sulfonates to form alkynes with increased number of carbon atoms.
(c)
Interpretation:
The structure and the name of the product formed from the reaction between propynyl magnesium bromide and ethylene oxide is to be stated.
Concept introduction:
Ethylene oxides react with Grignard reagent to give primary alcohols. Ethylene oxide undergoes ring-opening reaction. In the Grignard reagent, the carbon atom which is bonded to magnesium atom behaves as a nucleophile and the magnesium atom behaves as a Lewis acid. Magnesium atom gets attach to oxygen atom, making it a good leaving group by Protonation.
(d)
Interpretation:
The structure and the name of the product formed from the reaction between methyl sodium acetylide and is to be stated.
Concept introduction:
Alkylenic anions are stronger bases. They can easily donate electrons due to the presence of bonds and the negative charge. They react with alkyl halides or sulfonates to form alkynes with increased number of carbon atoms.
