The space shuttle orbiter utilizes the oxidation of methyl hydrazine by dinitrogen tetroxide for propulsion: Use bond energies to estimate H for this reaction. The structures for the reactants are:
Chem Notes Bonding In Lewis Dot Theory, valence electrons are represented by dots In VSEPR Theory, you know the basic shape and bond angels of molecules In Valence Bonding Theory, you know which orbitals are used to form bonds Valence Bonding Theory Overlapping orbitals form bonds Each of the overlapping orbitals must have a single electron Each of these electrons must have opposite spins In order to get the correct bond angles for the molecular geometry of a molecule, you have to have hybrid orbitals. o VSEPR Theory tells you which shapes and bond angles you need Atoms can only use their own orbitals when hybridizing. o Normal P orbitals look like dumbbells.
