Consider molecule A shown below. Remember that for a Lewis structure, you must show all atoms, all bonding valence electrons, all nonbonding valence electrons, and all nonzero formal charges.

Using Lewis structures for reactants and products and using curved arrows to show the flow of electrons in molecule A, give the chemical equation that shows the heterolytic dissociation of one of the three CH bonds in molecule A to give H^{+} and the corresponding conjugate base. If resonance structures exist for the conjugate base, give all important resonance structures for the conjugate base. Clearly give the numerical value of the HCC bond angle in this conjugate base of molecule A.
