3) In a far away land and long ago, a series of experiments were carried out. Three samples of minerals where collected, and the sample were analyzed, and found to contain two elements kalium and pyron. . They use K for kalium and HO for pyron. Sample..... A (from a mine). .

Criteria for success All molecular drawings must be valid Lewis structures (octet rule, formal charge, valence, geometry). Curved arrows will be interpreted very strictly. Thus, they must clearly indicate the origin and destination of electron delocalization. Tasks 1. Generate at least three reasonable resonance contributors of the molecule in Fig. 3. 2. Rank reasonance contributors from least significant to most significant (#1 = most significant) and explain your choice. 3. Are the lone pairs of electrons on alcohol groups localized or delocalized? Briefly explain. HO OH F Figure 3: Molecule with delocalized electrons
