Solution: Formation of sp3 hybrid orbitals.Which of the p orbitals do you think contributes the most in the mixing that leads to the right-most sp3 hybrid orbital in the second row of the figure?

Problem


An s orbital appears as a sphere centered on the x y z axes.  Each of the three p orbitals appears as two egg-shaped balloons connected end-to-end, centered on the x y z origin.  The p x orbital lies on the x-axis, the p y orbital is on the y-axis, and the p z orbital is on the z-axis. The one s and three p orbitals hybridize to form four sp3 hybrid orbitals.  Each hybrid appears as a small egg-shaped lobe attached to a large egg-shaped lobe.  Each sp3 hybrid is arranged toward a different point of a pyramid, which when shown together (large lobes only) appears as four lobes in the shape of a pyramid, separated by 109.5 degree angles.
