The correct answer is the Galápagos Islands.
Each sp2<span> hybrid orbital on a carbon atom contains one electron. Figure 9.21 shows how the four C</span><span>H </span><span> bonds are formed by overlap of </span>sp2<span> hybrid orbitals on C with the 1</span>s<span> orbitals on each H atom. We use eight electrons to form these four electron-pair bonds. The C</span><span>C </span><span> bond is formed by the overlap of two </span>sp2<span> hybrid orbitals, one on each carbon atom, and requires two more electrons. The C</span>2H4<span> molecule has a total of 12 valence electrons, 10 of which form the one C</span>C and the four C<span>H </span><span> bonds.</span>
