1.

If H_(2) molecule is acting as ligand via oxidate addition : [Ir^(I)(CO)ClL_(2)] ("Vaska's complex")+H_(2) to [Ir^(III)(CO)Cl(H_(2))L_(2)],L=PPh_(3) then, choose the correct statement about the H_(2) molecule fate before and after reaction .

Answer»

`{:("Before","Trasition State","After"),(B.O=1,1 sigma"-DONOR,"sigma(**)-"ACCEPTOR",B.O.=0):}`
`{:("Before","Trasition State","After"),(B.O=1,1 sigma"-donor,"sigma(**)-"acceptor",B.O.=1):}`
`{:("Before","Trasition State","After"),(B.O=1,1 sigma"-donor,"pi(**)-"acceptor",B.O.=0):}`
`{:("Before","Trasition State","After"),(B.O=1,1 sigma^(**)"-donor,"sigma-"acceptor",B.O.=0):}`
