Which of these statements is false? (A) Acetylene (ethyne) can be converted to the acetylide anion by treating with a strong bas
e such as NaNH2. (B) Acetylene (ethyne) can be converted to the acetylide anion by treating with a strong base such as NaOH. (C) Acetylene (ethyne) can be converted to the acetylide anion by treating with a strong base such as CH3Li.
(C) Acetylene (ethyne) can be converted to the acetylide anion by treating with a strong base such as CH₃Li.
Explanation:
Acetylene (C₂H₂) can be converted to the acetylide anion (C₂⁻²) when treated with a base because it will donate protons (2H⁺). So it will be a neutralization reaction. NaNH₂ and NaOH are strong bases because they are good electrons donators ( NaNH₂ has pair of electrons on N, and NaOH has the group OH⁻), but CH₃Li has no pair of electrons to donate, so it's not a strong base.
