(a)
Interpretation: The number of lone pairs in TeCl2 molecule needs to be determined.
Concept Introduction:
Lewis dot structure or electron dot structure can be defined as the structure of a molecule in which all the valence electrons and lone pairs on each atom is represented with the help of line and dot or cross.
The Lewis structure is used to predict the hybridization and molecular geometry of the molecule as it gives complete idea about the bonding between bonded atoms in a molecule.
(a)
Answer to Problem 6E
8 lone pairs; 
Explanation of Solution
The number of lone pairs in any molecule can be determined with the help of Lewis structure. In the Lewis structure of TeCl2 molecule;
Number of valence electrons in Te = 6 electrons
Number of valence electrons in Cl = 7
Total number of valence electrons = 6 + (2 x 7) = 20 electrons.
Thus the Lewis structure must be:
Hence in TeCl2 molecule there are 8 lone pairs.
(b)
Interpretation: The number of lone pairs in HI molecule needs to be determined.

Answer to Problem 6E
3 lone pairs; 
Explanation of Solution
The number of lone pairs in any molecule can be determined with the help of Lewis structure. In the Lewis structure of HI molecule;
Number of valence electrons in I = 7 electrons
Number of valence electrons in H= 1
Total number of valence electrons = 1 + (1 x 7) = 8 electrons.
Thus the Lewis structure must be:
Hence in HI molecule there are 3 lone pairs.
(c)

Answer to Problem 6E
10 lone pairs; 
Explanation of Solution
The number of lone pairs in any molecule can be determined with the help of Lewis structure. In the Lewis structure of AsBr3 molecule;
Number of valence electrons in As = 5 electrons
Number of valence electrons in Br = 7
Total number of valence electrons = 5 + (3 x 7) = 26 electrons.
Thus the Lewis structure must be:
Hence in AsBr3 molecule there are 10 lone pairs.
(d)
Interpretation: The number of lone pairs in SiF4 molecule needs to be determined.
Concept Introduction:

(d)
Answer to Problem 6E
12 lone pairs; 
Explanation of Solution
The number of lone pairs in any molecule can be determined with the help of Lewis structure. In the Lewis structure of SiF4 molecule;
Number of valence electrons in Si = 4 electrons
Number of valence electrons in F = 7
Total number of valence electrons = 4 + (4 x 7) = 32 electrons.
Thus the Lewis structure must be:
Hence in SiF4 moleculethere are 12 lone pairs.
(e)
Interpretation: The number of lone pairs in F2 molecule needs to be determined.
Concept Introduction:
Lewis dot structure or electron dot structure can be defined as the structure of a molecule in which all the valence electrons and lone pairs on each atom is represented with the help of line and dot or cross.
The Lewis structure is used to predict the hybridization and molecular geometry of the molecule as it gives complete idea about the bonding between bonded atoms in a molecule.
(e)
Answer to Problem 6E
6 lone pairs; 
Explanation of Solution
The number of lone pairs in any molecule can be determined with the help of Lewis structure. In the Lewis structure of F2 molecule;
Number of valence electrons in F = 7
Total number of valence electrons = (2x 7) = 14 electrons.
Thus the Lewis structure must be:
Hence in F2 molecule there are 6 lone pairs.

- 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. diarrow_forwardProblem 3.
