(a)
Interpretation: The Lewis electron dot structure for and VESPER model should be determined for the following molecule.
Concept Introduction:
VSEPR theory has certain advantages over Lewis dot structures. Some of them are described as below:
Lewis structures are effective in prediction about number of covalent bonds formed by an atom. However, Lewis structure does not give precise representation of electron density in molecule.
According to VSEPR theory ,
No of hybrid orbitals ,H= (V+S-C+A)/2
Where H = No of the central atom
S= No of single valency atoms
C= No of cation
A= No of anions
Bond pair of electrons doesn’t remains stationary as Lewis formula suggests.
(b)
Interpretation: The Lewis electron dot structure for and VESPER model should be determined for the following molecule.

Chemistry & Chemical Reactivity
- It is possible to write a simple Lewis structure for the SO42- ion, involving only single bonds, which follows the octet rule. However, Linus Pauling and others have suggested an alternative structure, involving double bonds, in which the sulfur atom is surrounded by six electron pairs. (a) Draw the two Lewis structures.
