Shape of H2SO4

  1. 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

  3. 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.
     
  4. 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
     
  5. Hint: Look at your electron count and then look at the charge on sulfuric acid.
