Cyclopropane (C3H6) has the shape of a triangle in which a C atom is bonded to two H atoms and two other C atoms at each corner. Cubane (C8H8) has the shape of a cube in which a C atom is bonded to one H atom and three other C atoms at each corner.
(a) Draw Lewis structures of these molecules.
(b) Compare the CCC angles in these molecules with those predicted for an sp3-hybridized C atom.
(c) Would you expect these molecules to be easy to make?
