A) Propyne
B) Ethene
C) Prppene
D) Ethyne
Correct Answer: A
Solution :
Alkynes on hydration give ketones except ethyne that gives aldehyde. Hence, propyne gives ketone. \[C{{H}_{3}}-C=CH\xrightarrow{{{H}_{2}}O}C{{H}_{3}}-\overset{OH}{\mathop{\overset{|}{\mathop{C}}\,}}\,=C{{H}_{2}}\] \[\xrightarrow{\text{Tautomerises}}\underset{\text{ketone}}{\mathop{C{{H}_{3}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,=C{{H}_{3}}}}\,\]
