Regarding the catalytic cycle of hydrogenation of alkanes involving Rh...
Catalytic cycle of hydrogenation of alkanes involving RhCl(PPh3)3 as the catalyst:
Formation of 16-electron Rh intermediate:
- RhCl(PPh3)3 acts as a source of Rh(I) ion that reacts with H2 to form Rh(H)Cl(PPh3)3.
- The Rh(H)Cl(PPh3)3 intermediate reacts with alkane to form Rh(alkane)(Cl)(PPh3)2, which is a 16-electron Rh intermediate.
Formation of 18-electron Rh intermediate:
- The 16-electron Rh intermediate then reacts with H2 to form a dihydride intermediate, Rh(H)2(alkane)(Cl)(PPh3)2.
- The dihydride intermediate then reacts with another H2 to form the 18-electron Rh intermediate, Rh(alkane)(H)2(Cl)(PPh3)2.
Product formation:
- The 18-electron Rh intermediate then reacts with another molecule of alkane to release the product, along with the regeneration of the 16-electron Rh intermediate.
- The 16-electron Rh intermediate can then undergo another cycle of hydrogenation with H2 to form the dihydride intermediate and then the 18-electron intermediate, leading to the formation of more product.
Therefore, in the catalytic cycle of hydrogenation of alkanes involving RhCl(PPh3)3 as the catalyst, both 16-electron and 18-electron Rh complexes are involved. Hence, option 'D' is the correct answer.

- The dihydride intermediate then reacts with another H2 to form the 18-electron Rh intermediate, Rh(alkane)(H)2(Cl)(PPh3)2.

[RhCl(PPh3)3] has originally 16 electron when found through neutral method. For stability 18e are needed which are found when it reacts with alkene during reaction.
