Problem 84E

In the Chemistry and the Environment box on free radicals in this chapter, we discussed the importance of the hydroxyl radical in reacting with and eliminating many atmospheric pollutants. However, the hydroxyl radical does not clean up everything. For example, chlorofluorocarbons—which destroy stratospheric ozone—are not attacked by the hydroxyl radical. Consider the hypothetical reaction by which the hydroxyl radical might react with a chlorofluorocarbon:

Use bond energies to explain why this reaction is improbable.

Step-by-Step Solution:
Step 1 of 3

Solution:Step-1(a) I has atomic number 53, [Kr] 4d 5s 5p 10 2 5 Br has atomic number 35 [Ar] 3d 4s 4p 10 2 5Thus, the valence atomic orbitals of I is 5s , 5p , 5p and 5p .xhe vyence atomizorbitals of Br is4s, 4p x4p ay 4p . zStep-2(b) Bond order of IBrThe MO electronic configuration of IBr is similar to that of F . 2 2 2 2 2 2 2 2 2 2 1s *1s 2s *2s 2px 2py 2pz *2px *2py 108Thus the bond order= 2 = 1Step-3(c)The orientation of the overlapping of atomic orbitals depends on the atomic size. This twogiven atomic orbitals are of different sizes because the size of I is larger than that of Br.Step-4(d)The given MO shows , formation of bond by by the head on overlapping of two *p zatomic orbitals.Step-5(e)There is no electron present in the given structure of MO of IBr molecule.
