Basic Information

Molecule Name: Sulfuric Acid
Formula: H2SO4

H2SO4, or Sulfuric Acid, is a molecule composed of Hydrogen, Sulfur, and Oxygen. It is commonly used in lead batteries for cars, and for the removal of rust in the iron and steelmaking industry. Below is information pertaining to this molecule.

Dash Model

In the dash model, arrows are drawn from the element with the lower electronegativity value, to the element of the higher value.

Lewis Structure

The Lewis Structure for this molecule would be:

VSEPR Model & Formula

The VSEPR model of an element depicts how the valence electron pairs surrounding an atom that repel one another. Therefore, the orbitals containing the electron pairs are located as far apart as possible. The model for H2SO4 is:



Each of the valence electrons are located at a 109.5 degree angle away from one another. The formula for this depiction would be AX4.

Covalent Bonds

The covalency in bonds is dependant on the diffence in negativity values in the present elements. For example:

With the given values and find the differnce between each molecule that is bonded together with another. In H2SO4 the H is bonded to the O. By subracting the values of these two elements, the covalency of the bond is revealed.

Oxygen also bonds with Sulfur in H2SO4, and the covalency of this bond is also able to be obtained.

Polarity

Polarity is the generally used to speak about the negative and positive characteristics associated with electrical charges of an a molecule.

The molecule is polar, as it has one end positively charged, and the other negatively charged. Hydrogen has a positive charge, and oxygen has a negative charge, causing the molecule to have both charges making it polar. 

Bonds

The forces bonding these molecules together, at the pink arrow, include: Dipole-Dipole, Hydrogen Bond, and London Dispurssion.

• Dipole-Dipole is the bond which occurs between a postively charged end of one molecule, and a negatively charged end of another.
• Hydrogen Bond is a dipole-dipole attraction, between the H of one molecule and the O, F, or N, of another. It is represented in a picture by a dotted line.
• London Dispurssion occurs in every molecule attraction. This is due to the fact that a electrons are constantly moving around the molecule influencing a change in the poles, causing a temporary pole.
