A) Bromine water
B) Aqueous \[NaOH\]
C) Fehlings solution
D) Ammoniacal \[AgN{{O}_{3}}\]
Correct Answer: D
Solution :
Key Idea: [a] Bromine water is used to distinguish between saturated and unsaturated compounds. [b] Aqueous \[NaOH\] is used to distinguish between hydrocarbons and ethers. [c] Fehlings solution is used to distinguish between aldehyde and ketone [d] Ammoniacal \[AgN{{O}_{3}}\] is used to distinguish between terminal and non-terminal alkynes. \[C{{H}_{3}}-C{{H}_{2}}-C\equiv CH+AgN{{O}_{3}}\xrightarrow{{}}\] \[\underset{white\text{ }ppt.}{\mathop{C{{H}_{3}}-C{{H}_{2}}-C\equiv CAg}}\,\] \[C{{H}_{3}}-C\equiv C-C{{H}_{3}}+AgN{{O}_{3}}\xrightarrow{{}}\] no reaction \[AgN{{O}_{3}}\] reacts with only terminal alkynes due to presence of acidic hydrogen.
