Which statement is/are true about acetylide anions?
A)The alkylated product is poor with secondary alkyl halides.
B)Primary alkyl halides are best suited for alkylation.
C)In the presence of tertiary alkyl halides,the acetylide anion acts as base to give an elimination product.
D)Only two of these statements are true.
E)All of the statements are true.

Question

Quizplus · Accepted Answer

Acetylide anions are strong bases and nucleophiles. They react poorly with secondary alkyl halides due to steric hindrance, making primary alkyl halides the best substrates for alkylation reactions. With tertiary alkyl halides, acetylide anions tend to act as bases, leading to elimination products rather than substitution. Therefore, all the statements provided are true regarding the behavior of acetylide anions in different contexts.
