Question

$Ph-C\equiv C-CH_{3}\overset{H g^{2 +} / H^{+}}{ \rightarrow }A$
What is the product (A) for above reaction?

• A.
  
• B.
  
• C.
  
• D.
  

Answer 1

Answer: (C)

$Ph-C\equiv C-CH_{3}\overset{H g^{2 +} / H^{+}}{ \rightarrow }$
The product formed undergoes tautomerization to give the more stable enol form.
