1) Draw 3 different Lewis structures for a compound with the molecular formula C6H14O; then draw both the condensed formula and the line-angle structure for each.
2) Use resonance structures to show why acetate (CH3COO-) is more stable than ethoxide (CH3CH2O-); what does this say about the relative acidity of acetic acid and ethanol (their respective conjugate acids)?
