1 Ferrocene

2

C a C_{2}

3 Tetraethyl lead

(T E L)

4 All of these

COORDINATION COMPOUNDS

28799 Which of the following does not have a metal carbon bond

1

K [P t (C_{2} H_{4}) C l_{3}]

2

N i (C O)_{4}

3

A l (O C_{2} H_{5})_{3}

4

C_{2} H_{5} M g B r

Explanation:

(c) $A l (O C_{2} H_{5})_{3}$ contains bonding through $O$ and thus it does not have metal-carbon bond.

COORDINATION COMPOUNDS

28800 Coordination compounds have great importance in biological systems. In this context which of the following statements is incorrect

1 Cyanocobalamin is

B_{12}

and contains cobalt.

2 Haemoglobin is the red pigment of blood and contains iron.

3 Chlorophylls are green pigments in plants and contains calcium.

4 Carboxypepticase

- A

is an enzyme and contains zinc.

COORDINATION COMPOUNDS

28801 Ziegler-Natta catalyst is

1

(P h_{3} P)_{3} R h C l

2

K [P t C l_{3} (C_{2} H_{4})]

3

[A l_{2} (C_{2} H_{6})_{6}] + T i C l_{4}

4

[F e (C_{2} H_{5})_{2}]

Explanation:

Ziegler Natta catalyst is a mixture of triethylaluminium and titanium tetrachloride i.e. $A l {(C_{2} H_{5})}_{3} + T i C l_{4}$ . It is used for polymerization of alkenes to produce polymers.
