The major industrial source of hydrogen gas is by the following reaction: Use bond energies to predict H for this reaction.
CHEM 220: Organic Chemistry Lewis Structures o Lewis structures help keep track of valence electrons of atoms and provide an easier understanding of reaction mechanisms. o Illustrates the transfer of electrons between atoms. o Helps calculate formal charge of an atom. Rules for Lewis Structures o First, determine the number of valence electrons for an atom and arrange them so there is one on each side before adding more. o Second, arrange the atoms to form bonds with each of the electrons, for something like CH 4ine up Hydrogen’s electrons with each of the valence electrons of carbons. It might be helpful to draw bond lines at this point (optional.) Formal Cha
