In summary, the conversation revolved around the use of VSERP to draw the shape of H2SO4 and the electron count needed for its structure. The structure was discussed, with the S as the central atom and the remaining atoms attached to it with different types of bonds. However, despite the calculations, the resulting electron count did not match the charge on sulfuric acid, indicating that the method may not work accurately.

I tried to use VSERP to draw the shape of H2SO4
but consider
S :6 (group6)
4O :2*4
2H :1*2
-----------
16=>4pi bond
but then 4 pi bond of oxygen=16 electrons
how about the sigma bond of 2 hydrogen

From memory SO4(-2) has the S as the central atom, two O's oppositely have a pi bond, and the remaining two have sigma bonds each with a negative charge. The H's are attached to these O's.

but then it becomes
S:6
2O:1*2(sigma)
2O:2*2(pi)
2H:1*2
----------
14
but 2pi+4sigma=16
again, it does not work

Hint: Look at your electron count and then look at the charge on sulfuric acid.
 

FAQs about Drawing H2SO4 with VSERP

1. What is H2SO4 and what does it stand for?
H2SO4 is the chemical formula for sulfuric acid, a highly corrosive and strong mineral acid. It stands for dihydrogen sulfate or simply sulfuric acid.

2. What is VSERP and how is it related to drawing H2SO4?
VSERP stands for Valence Shell Electron Pair Repulsion theory, which is used to predict the molecular geometry of molecules. Drawing H2SO4 with VSERP allows us to see the arrangement of atoms and electron pairs in the molecule.

3. How do I draw the Lewis structure of H2SO4 with VSERP?
First, determine the number of valence electrons for each element (2 for H, 6 for S, and 24 for O). Then, arrange the atoms in a way that follows the octet rule (except for sulfur, which can have more than 8 valence electrons). Finally, use VSERP to determine the molecular geometry by considering the repulsion between electron pairs.

4. Can VSERP be used for other molecules besides H2SO4?
Yes, VSERP can be used to draw the Lewis structures of many different molecules. It is especially useful for molecules with multiple bonds and/or lone pairs of electrons.

5. Why is it important to know the molecular geometry of H2SO4?
Knowing the molecular geometry of H2SO4 can help us understand its physical and chemical properties, such as its acidity and reactivity. It can also help us predict how it will interact with other molecules in a chemical reaction.
