Benzene is a special case of conjugation that leads to an especially stable bonding arrangement. The benzene ring consists of six sp2 hybridized carbon atoms in a regular hexagon. Each carbon forms two σ-bonds with adjacent carbons‚ and a third σ-bond with a hydrogen atom. The 2p orbital on each atom is available for π-bonding. Interaction between the p orbitals on the six carbon atoms forms a conjugated system of π-electrons. Molecules with this bonding arrangement are called aromatic molecules

Copper-Iron Stoichiometry Lab Report 10/3/12 Abstract: The lab performed required the use of quantitative and analytical analysis along with limiting reagent analysis. The reaction of Copper (II) Sulfate‚ CuSO4‚ mass of 7.0015g with 2.0095g Fe or iron powder produced a solid precipitate of copper while the solution remained the blue color. Through this the appropriate reaction had to be determined out of the two possibilities. Through the use of a vacuum filtration system the mass of Cu was
