Week 10- Constitutional isomers Constitutional isomers have the same molecular formula, but their atoms are bonded in different orders. These may be further distinguished as chain isomers, which differ only in hydrocarbon chain structure, positional isomers, which differ in the location of a functional group, and functional group isomers which differ in the nature of their functional groups. Typically chain and position isomers show only modest differences in their physical and chemical properties, while functional group isomers differ greatly from...

1. The molecules PF5 and AsF5 exist, but the analogous molecule NF5 does not. Why not? 2. For the molecule N2O there are five unique Lewis structures that satisfy the octet rule. Three have the N-N-O bond skeleton and two would have the N-O-N skeleton. a) Draw the five UNIQUE Lewis structures. b) By considering the formal charges, can you suggest which structures could be eliminated due to low stability (i.e. have like charges next to each other). c) Which...
