2. For a molecular formula of C5H6O: a) Draw Lewis structures, showing all bonding and non-bonding electrons, for one compound with an alcohol functional group; one with an ether functional group; one with a ketone functional group; and one with an aldehyde functional group. b) For each compound, indicate all bond angles and build a molecular model. c) Indicate whether each pair of valence electrons is non-bonding (n) or σ- or - bonded. For each atom, indicate the corresponding orbitals that are involved (e.g. nsp3, Osp3-sp3, etc.).

4. One of the resonance structures of "tropylium ion" (C7H7*) is shown below. It is planar and aromatic with Hückel number of p-n electrons where n=1. Draw all the other contributing resonance structures. (There are more than two.) Based on the “average" of the contributing resonance structures, how close does the average ring carbon get to its "octeť" in tropylium ion?
