Solution
To determine the products when 1-bromobutane is treated with sodium acetylide, follow these steps:
- Identify the reactants: 1-bromobutane (C4H9Br) and sodium acetylide (NaC≡CH).
- Recognize the type of reaction: This is a nucleophilic substitution reaction where the acetylide ion (C≡C⁻) will replace the bromine atom in 1-bromobutane.
- Write the reaction equation: C4H9Br + NaC≡CH → C4H9C≡CH + NaBr
- Determine the product: The product formed is 1-hexyne (C4H9C≡CH) and sodium bromide (NaBr).
Therefore, the predominant products are 1-hexyne and NaBr. The correct answer is:
1-hexyne and NaBr
