If cyclobutane were flat, it would have exactly 90 degree bond angles and could theoretically use only p orbitals to form its C-C bonds.
- Propose a hybridization scheme for the carbon atoms in this hypothetical flat butane that would allow all the C-H bonds to be equivalent.
- Exactly where would the hydrogens on each carbon be located?
- What features of the real cyclobutane contradict this hypothesis?
