निम्न में से कौनसे कार्बोनिल यौगिक को \(HgSO _{4}\) तथा \(H _{2} SO _{4}\) की उपस्थिति में ऐल्काइन पर जल के योग द्वारा नहीं बनाया जा सकता है ?

  1. A \(\begin{array}{*{20}{c}} {\,\,\,\,\,\,O} \\ {\,\,\,\,\,\,||} \\ {C{H_3} - C - H} \end{array}\)
  2. C \(\begin{array}{*{20}{c}} {\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,O} \\ {\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,||} \\ {C{H_3} - C{H_2} - C - H} \end{array}\)
  3. D \(\begin{array}{*{20}{c}} {O\,\,\,\,\,\,\,\,\,} \\ {||\,\,\,\,\,\,\,\,\,\,} \\ {C{H_3} - C - C{H_2}C{H_3}} \end{array}\)

Answer & Solution

Correct Answer

(C) \(\begin{array}{*{20}{c}} {\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,O} \\ {\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,||} \\ {C{H_3} - C{H_2} - C - H} \end{array}\)

Step-by-step Solution

Detailed explanation

Reaction of \(HgSO _{4} / dil H _{2} SO _{4}\) with alkyne gives addition of water as per markonikoff's rule. \((1)\) \(HC \equiv CH\) \(\xrightarrow[{{H_2}S{O_4}}]{{HgS{O_4}}}\)…
