1) Draw Lewis structures for all 6 structural and geometric isomers of c4h8. (Hint: Each of the isomers will contain exactly one double bond or ring.)
2.) Two of the isomers have C-C-C bond angles that deviate significantly from those predicted by VSEPR theory. On this basis, which isomer would you predict is the least stable one? the second least stable?
