Ammoniacal silver nitrate forms a white precipitate easily with
- A \(\mathrm{CH}_3 \mathrm{CH}=\mathrm{CH}_2\)
- B \(\mathrm{CH}_3 \mathrm{C}=\mathrm{CCH}_3\)
- C \(\mathrm{CH}_3 \mathrm{C}=\mathrm{CH}\)
- D \(\mathrm{CH}_2=\mathrm{CH}_2\)
Answer & Solution
Correct Answer
(C) \(\mathrm{CH}_3 \mathrm{C}=\mathrm{CH}\)
Step-by-step Solution
Detailed explanation
Ammoniacal silver nitrate, also known as Tollens reagent, reacts with terminal alkynes to form a white precipitate of silver acetylide. The general reaction is \(R-C\equiv CH + [Ag(NH_3)_2]^+ OH^- \rightarrow R-C\equiv C-Ag \downarrow + 2NH_3 + H_2O\). Among the given options,…
