Match List I with List II

LIST-I (Substances)
A. Ziegler catalyst
B. Blood Pigment
C. Wilkinson catalyst
D. Vitamin B₁₂

LIST-II (Element Present)
I. Rhodium
II. Cobalt
III. Iron
IV. Titanium

Choose the correct answer from the options given below:

Answer: A → IV, B → III, C → I, D → II

Solution

Ziegler catalyst:

TiCl_{4}

-based -- Titanium (IV)

Blood pigment (haemoglobin): Iron (III)

Wilkinson's catalyst:

RhCl(PPh_{3})_{3}

-- Rhodium (I)

Vitamin

B_{12}

: Cobalt (II)

So A-IV, B-III, C-I, D-II.

Key confirmed: A-IV, B-III, C-I, D-II.
