Ammoniacal silver nitrate forms a white precipitate easily with
- A \(\mathrm{CH}_3 \mathrm{C}=\mathrm{CH}\)
- B \(\mathrm{CH}_3 \mathrm{C}=\mathrm{CCH}_3\)
- C \(\mathrm{CH}_3 \mathrm{CH}=\mathrm{CH}_2\)
- D \(\mathrm{CH}_2=\mathrm{CH}_2\)
Answer & Solution
Correct Answer
(A) \(\mathrm{CH}_3 \mathrm{C}=\mathrm{CH}\)
Step-by-step Solution
Detailed explanation
In general, \(\mathrm{C}_2 \mathrm{H}_2\) and all 1-alkynes given white precipitate with ammoniacal silver nitrate. Thus, in this question, propyne-1 \(\left(\mathrm{CH}_3 \mathrm{C}=\mathrm{CH}\right)\) will give white precipitate with ammoniacal silver nitrate.
