The catalytic cycle for the rhodium-catalyzed oxo reaction is shown below. Starting in the upper left-hand corner (with the complex in the red box) please label each of the 8 steps in the reaction with the type of reaction(s) taking place. (Note: each step in the cycle is reversible, but you only have to describe theforward reaction (going in the clockwise direction).

refer to image, answer all parts and explain, will rate.

For Step (1) and (2), Draw the Structure OF the product For both of them. OH (1) Ts Cl, PY (2) Na SH,DMSO
