Which compound will react with an aqueous solution of ${\rm{Ag}}\left( {{\rm{N}}{{\rm{H}}_3}} \right)_2^ + {\rm{O}}{{\rm{H}}^ - }$?

${\rm{C}}{{\rm{H}}_3}{\rm{C}}{{\rm{H}}_2}{\rm{C}} \equiv {\rm{CH}}$

${\rm{C}}{{\rm{H}}_3}-{\rm{C}} \equiv {\rm{C}}-{\rm{C}}{{\rm{H}}_3}$

${\rm{C}}{{\rm{H}}_3}-{\rm{C}}{{\rm{H}}_3}$

${\rm{C}}{{\rm{H}}_2} = {\rm{C}}{{\rm{H}}_2}$

Which compound will react with an aqueous solution of

\mathrm{Ag}\left( {\mathrm{N}{\mathrm{H}_3}} \right)_2^ + \mathrm{O}{\mathrm{H}^ - }

View answer and explanation

Correct option: B

\mathrm{C}{\mathrm{H}_3}\mathrm{C}{\mathrm{H}_2}\mathrm{C} \equiv \mathrm{CH}

Option B (

CH_3CH_2C \equiv CH

) is correct because terminal alkynes react with Tollens' reagent (

Ag(NH_3)_2^+ OH^-

) to form a silver acetylide precipitate.
