An unsaturated hydrocarbon XX absorbs two hydrogen molecules on catalytic hydrogenation, and also gives following reaction:
X→(ii)ZnH2O(i)O3A→[Ag(NH3)2]+BX\mathop{\to}_{\dfrac{\left(ii\right)Zn}{{H}_{2}O}}\left(i\right){O}_{3}A\overset{{\left[Ag{\left({NH}_{3}\right)}_{2}\right]}^{+}}{\to}B (3-oxo-hexanedicarboxylic acid) XX will be:An unsaturated hydrocarbon X absorbs two hydrogen molecules on catalytic hydrogenation, and also gives followingAn unsaturated hydrocarbon X absorbs two hydrogen molecules on catalytic hydrogenation, and also gives followingAn unsaturated hydrocarbon X absorbs two hydrogen molecules on catalytic hydrogenation, and also gives followingAn unsaturated hydrocarbon X absorbs two hydrogen molecules on catalytic hydrogenation, and also gives followingAn unsaturated hydrocarbon X absorbs two hydrogen molecules on catalytic hydrogenation, and also gives following

Options

  1. AMatch the column I with column II and mark the appropriate choice. Column I Column II (p) NaH (i) Interstitial hydride
  2. BMatch the column I with column II and mark the appropriate choice. Column I Column II (p) NaH (i) Interstitial hydride
  3. CMatch the column I with column II and mark the appropriate choice. Column I Column II (p) NaH (i) Interstitial hydride
  4. DMatch the column I with column II and mark the appropriate choice. Column I Column II (p) NaH (i) Interstitial hydride

Correct answer

C. Match the column I with column II and mark the appropriate choice. Column I Column II (p) NaH (i) Interstitial hydride

Step-by-step solution

Since X absorb two molecules of hydrogen on cataytic hydrogenation, it shoulf have to two double bonds.

Initial reaction is ozonolysis.

An unsaturated hydrocarbon X absorbs two hydrogen molecules on catalytic hydrogenation, and also gives following
