Change of catalyst changed products
`CO + 3H_2 overset(N i)(rarr) X + H_2O`
`CO + 2H_2 underset(Cr_2O_3)overset(Cu//ZnO)(rarr)Y`
`CO + H_2 overset(Cu)(rarr)Z`.
The magnitude of the algebraic sum of the oxidation state of carbon in X, Y and Z is _____

Text Solution

Verified by Experts

The correct Answer is:
6
`CO + 3H_2 overset(N i)(rarr) overset(-4)(CH_4) + H_2O , CO + 2H_2 + underset(Cr_2O_3)overset(Cu//Zn)(rarr) overset(-2)(CH_3)OH`
`CO + H_2 overset(Cu)(rarr)Hoverset(0)(C)HO ,` total oxidation no - 4 - 2 = -6
