Question

Incorrect match among the following is:

• A. Cis-platin $–Pt$
• B. Wilkinson catalyst $-Rh$
• C. Vitamin $B_{12}–Cu$
• D. Chorophyll $-Mg$

Answer 1

The correct option is C Vitamin $B_{12}–Cu$

$\Rightarrow$ Vitamin $B_{12}$ also known as cobalamin with molecular formula $C_{63}{H}_{88}Co{N}_{14}{O}_{14}P$.

$\Rightarrow$ Cis-platin is a diamminedichloro platinum compound i.e.,


$\Rightarrow$ Wilkinson catalyst is the common name for chloridotris(triphenylphosphine) rhodium (I) a coordination complex of rhodium with the molecule formula $\left[RhCl\right(PP{h}_3{)}_3]$

$\Rightarrow$ Chlorophyll contains a magnesium ion encased in a large ring structure known as chlorin. Four nitrogen atoms from the chlorin surround and bind the magnesium atom.
