What are the relationships among bond order, bond energy, and bond length? Which of these can be measured? Distinguish between the terms paramagnetic and diamagnetic. What type of experiment can be done to determine if a material is paramagnetic?

Short Answer

Expert verified

The bond energy increases with the bond order and bond length decreases with increasing bond order. The bond length can be measured by using x-ray diffraction. The difference between the terms paramagnetic and diamagnetic is that paramagnetic causes the substance to be attracted towards the including magnetic field while diamagnetism causes the substance to be repelled from the inducing magnetic field. If a material is paramagnetic, it will be heavier in the tube in electromagnetic because the material will attract towards the magnetic field.

Why are d orbitals sometimes used to form hybrid orbitals? Which period of elements does not use d orbitals for hybridization? If necessary, which d orbitals (3d, 4d, 5d, or 6d) would sulphur use to form hybrid orbitals requiring d atomic orbitals? Answer the same question for arsenic and for iodine.

Carbon monoxide (CO) forms bonds to a variety of metals and metal ions. Its ability to bond to iron in haemoglobin is the reason that (CO) is so toxic. The bond carbon monoxide forms to metals is through the carbon atom:

M-Cโ‰กO

a. On the basis of electronegativities, would you expect the carbon atom or the oxygen atom to form bonds to metals?

b. Assign formal charges to the atoms in CO. Which atom would you expect to bond to metal on this basis?

c. In the MO model, bonding MOs place more electron density near the more electronegative atom. (See the HF molecule, Figs.14.45 and 14.46.) Antibonding MOs place more electron density near the less electronegative atom in the diatomic molecule. Use the MO model to predict which atom of carbon monoxide should form bonds to metals.
