The formal charge is the "charge" an element would have in a molecule or ion if all of the bonding electrons were shared equally between atoms. We can draw three inequivalent Lewis structures for the sulfite ion, SO3²-. The concepts of formal charge and electronegativity can help us choose the structure that is the best representation. 1.

Pass a piece of paper around the group and ask each group member in turn to perform the next step in the process of determining a correct Lewis structure (including formal charges on all atoms and resonance structures, if appropriate) for the following molecules and ions: N2H4, CCl4, CO3 2-, and NH4 +.

The molecule 2-butene, C4H8, can undergo a geometric change called cis-trans isomerization. (Figure 1) Such transformations can be induced by light and are the key to human vision. Rotation about the C=C bond, which breaks the π bond, is required for the isomerization. The average bond energy (enthalpy) for a C=C double bond is 614 kJ/mol and that of a C−C single bond is 348 kJ/mol. Estimate the energy needed to break only the π bond of the double bond of 2-butene.Express your answer numerically in joules per molecule.
