An organometallic compound amongst the following is
1 Ferrocene
2 \(Ca{C_2}\)
3 Tetraethyl lead \( (TEL)\)
4 All of these
Explanation:
It’s obvious.
COORDINATION COMPOUNDS
28799
Which of the following does not have a metal carbon bond
1 \(K[Pt({C_2}{H_4})C{l_3}]\)
2 \(Ni{(CO)_4}\)
3 \(Al{(O{C_2}{H_5})_3}\)
4 \({C_2}{H_5}MgBr\)
Explanation:
(c)\(Al{(O{C_2}{H_5})_3}\) 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.
Explanation:
(c)Chlorophyll are green pigment in plant & contain magnesium instead of calcium.
COORDINATION COMPOUNDS
28801
Ziegler-Natta catalyst is
1 \({(P{h_3}P)_3}RhCl\)
2 \(K[PtC{l_3}({C_2}{H_4})]\)
3 \([A{l_2}{({C_2}{H_6})_6}] + TiC{l_4}\)
4 \([Fe{({C_2}{H_5})_2}]\)
Explanation:
Ziegler Natta catalyst is a mixture of triethylaluminium and titanium tetrachloride i.e. \(Al \left( C _2 H _5\right)_3+ TiCl _4\). It is used for polymerization of alkenes to produce polymers.
