Which of the following option is incorrect regarding following process:

A)  'X' is an high spin complex

B)   it is Monds process

C)   'X' is tetrahedral in shape

D)   'X' is diamagnetic in nature

Correct Answer: A

Solution :

Mond?s process \[\underset{\text{(Impure)}}{\mathop{\overset{\text{(M)}}{\mathop{\text{Ni}}}\,\text{(s)+4CO(g)}}}\,\xrightarrow[{}]{\text{5}{{\text{0}}^{\text{o}}}\text{-6}{{\text{0}}^{\text{o}}}\text{C}}\underset{\text{(Volaitile)}}{\mathop{\overset{\text{(X)}}{\mathop{\text{Ni}}}\,{{\text{(CO)}}_{\text{4}}}\text{(g)}}}\,\] \[\xrightarrow[{}]{\text{15}{{\text{0}}^{\text{o}}}\text{-18}{{\text{0}}^{\text{o}}}\text{C}}\underset{\text{(Pure)}}{\mathop{\overset{\text{(M)}}{\mathop{\text{Ni}}}\,\text{(s)}}}\,\text{+4CO(g)(recycled)}\] \[\to \]Low spin complex / (Inner orbital complex)
