Which of the following statements are TRUE for covalent pi bonds? (Choose as many as apply. Hint: There are 4 correct answers!) Pi bonds arise from head-on overlap of two orbitals. Pi bonds arise from sideways overlap of two orbitals. The electron density in a pi bond is found above and below the axis between the two bonded nuclei. The electron density in a pi bond is found in between the two bonded nuclei. A pi bond can exist independently; not every pi bond is accompanied by an associated o bond. Pi bonds always exist in conjunction with an associated o bond; they can never exist independently. The pi bonds in a molecule determine the shape of the molecule. There can be more than one pi bond between two nuclei. Every covalent bond contains at least one pi bond.

The below picture is the electrostatic potential plot for valine molecule. The blue regions are areas of positive charge, the red regions are areas of negative charge, and the clear regions are areas of neutral charge. Comment on the charge distribution of valine and whether this makes sense based on the polarity of the bonds in the molecule. Additonally, explain there is negative charge  for oxygen and positive  charge for carbon
