with regard to resonance structures that are drawn for a real species which of the following statements is/are NOT true? A.) resonance structures are real molecules that co-exist in equilibrium with each other. B.) resonance structures differ in the location of their electrons, not the position of their atoms. C.) resonance structures are only drawings; each structure alone does not represent an existing molecule. D.) resonance structures all have electron localized structures, while the real species that is described by...

Which of the following statements is NOT true? Each pair of pi electrons in benzene is delocalized over 6 carbons All of the C-C bond lengths in benzene are identical. Benzene has a very high delocalization energy (resonance energy) compared with acyclic polyenes. In the presence of a catalyst, benzene undergoes addition by bromine to give a dibromide product.

Consider the following drawings: HË: HR- HD Co Which of the following statements are true? 1. The electrons in each molecule tend to orient themselves around the most electronegative element. II. Each molecular drawing follows the localized electron model. III. Both HF and Co, are linear molecules and therefore polar. IV. The bond angles of NH3 are slightly less than 109.5° because the lone pair compresses the angles between the bonding pairs. I, III, IV I, II, IV I, II,...
