A) Propanal
B) 2-propanal
C) Propanone
D) Propane diol
Correct Answer: C
Solution :
\[C{{H}_{3}}-C\equiv CH+{{H}_{2}}O\xrightarrow[1%\,HgS{{O}_{2}}]{dil\,\,{{H}_{2}}S{{O}_{4}}}\] \[\underset{Unstable}{\mathop{\left\{ C{{H}_{3}}-\underset{O-H}{\mathop{\underset{|}{\mathop{C}}\,}}\,=C{{H}_{2}} \right\}}}\,\xrightarrow{tautomerism}\] \[\xrightarrow{\text{Propyne}}\underset{Acetone\,\,\text{(Propanone)}}{\mathop{C{{H}_{3}}-\underset{O}{\mathop{\underset{||}{\mathop{C}}\,}}\,-C{{H}_{3}}}}\,\]
