Among the given boiling points, the correct boiling points corresponding to the stereoisomers of 1, 2-dichloroethylene are to be identified. Concept introduction: The dipole moment is defined as the charge separation between two the atoms in a covalent or in an ionic bond. Polarities of atoms or ions are known by dipole moment. If the value of dipole moment is zero, then the molecule is said to be non-polar, and if the value of dipole moment is not zero, then the molecule is said to be polar and possess permanent dipole moment. If any structure is symmetrical, then overall dipole moment will be zero, and the bond becomes non-polar. Also, a bond can be considered polar if there is some electronegativity difference between the atoms.

20. The Brusselator. This hypothetical system was first proposed by a group work- ing in Brussels [see Prigogine and Lefever (1968)] in connection with spatially nonuniform chemical patterns. Because certain steps involve trimolecular reac tions, it is not a model of any real chemical system but rather a prototype that has been studied extensively. The reaction steps are A-X. B+X-Y+D. 2X+ Y-3X, X-E. 305 It is assumed that concentrations of A, B, D, and E are kept artificially con stant so that only X and Y vary with time. (a) Show that if all rate constants are chosen appropriately, the equations de scribing a Brusselator are: dt A-(B+ 1)x + x²y, dy =Bx-x²y. di
