- 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 carbonucation.wiley.com/was/ui/v2/assessment-player/index.html?launchld=cfd75193-8ad7-481b-85f1-1edc9de58ca1#/question/11 A nitrogen atom can undergo sp? hybridization when it becomes part of a carbon-nitrogen double bond, as in H2C=NH. Your answer is correct. Select the sketch that shows the electron configuration of sp2 hybridized nitrogen just before the overlapping occurs to make this double bond: 1. sp 1. 2p v Correct. Using the following sketches (and the analogy to the double bond in C2Ha), describe the two bonds of the carbon-nitrogen double bond 88 The double bond consists of one sigma bond and one pi bond E Incorrect. Describe the geometry of H2C-NH by entering the expected bond angle for the bonds in this molecule.What will determine a change in the electric dipole moment of a molecule? What will determine a change of polarizability of a molecule during a vibration?
