Explanation:
In order to determine which of the given compounds does not have a metal-carbon bond, we need to examine the structure and bonding of each compound.
a) Al(OC2H5)3:
This compound contains aluminum (Al) bonded to three ethoxide groups (OC2H5). Each ethoxide group consists of a carbon atom bonded to three hydrogen atoms and an ethyl group (C2H5). The aluminum atom in this compound is connected to the oxygen atom through an oxygen-metal bond, not a metal-carbon bond. Therefore, compound a) does not have a metal-carbon bond.
b) C2H5MgBr:
This compound contains a magnesium (Mg) atom bonded to an ethyl group (C2H5) and a bromine atom (Br). The carbon atom in the ethyl group is directly bonded to the magnesium atom, forming a metal-carbon bond.
c) K[Pt(C2H4)Cl3]:
This compound contains a potassium ion (K+) and a complex ion consisting of a platinum (Pt) atom bonded to three chloride ions (Cl-) and an ethylene molecule (C2H4). The carbon atoms in the ethylene molecule are directly bonded to the platinum atom, forming metal-carbon bonds.
d) Ni(CO)4:
This compound contains a nickel (Ni) atom bonded to four carbon monoxide (CO) molecules. Each carbon atom in the carbon monoxide molecule is directly bonded to the nickel atom, forming metal-carbon bonds.
Conclusion:
Out of the given compounds, only compound a) Al(OC2H5)3 does not have a metal-carbon bond.
