The two isomers are: [Co(NH3)5ONO]Cl2 and [Co(NH3)5NO2]Cl2. 1. Draw Lewis structures for both isomers, making sure to highlight what the difference between them is, and what the charge on cobalt is. (Note: In your drawing, you don't have to draw the entire structure and all the bonds within each ammonia ligand (the N-H bonds), but you should for the NO2. It should be clear what atom from each ligand binds to the cobalt ion). 2. Which isomer do you expect...

Draw three-dimensional depictions of the following molecules. For each molecule provide theoretical bond angles, shape, and electron group geometry (ie octahedral, tetrahedral, bent, etc.). For each molecule, provide all possible structural and geometric isomers. If the molecule/ion possesses resonance structures, draw all relevant structures? What is the point group of each structure? If the compound is chiral, draw its enantiomer. NiCl2(NH3)2 (tetrahedral) PCl2F3 NO3-

Week 10- Constitutional isomers Constitutional isomers have the same molecular formula, but their atoms are bonded in different orders. These may be further distinguished as chain isomers, which differ only in hydrocarbon chain structure, positional isomers, which differ in the location of a functional group, and functional group isomers which differ in the nature of their functional groups. Typically chain and position isomers show only modest differences in their physical and chemical properties, while functional group isomers differ greatly from...

Draw a three dimensional structure for each compound, and star all asymmetric carbon atoms. Draw the mirror image for each structure, and state whether you have drawn a pair of enantiomers or just the same molecule twice. Draw the enantiomers of 1,3-dibromobutane and label them as (R) and (S).

1. [10 points) For the following sets of two-dimensional points, (1) draw a sketch of how they would be split into clusters by K-means for the given number of clusters and (2) indicate approximately where the resulting centroids would be. Assume that we are using the squared error objective function. If you think that there is more than one possible solution, then please indicate whether each solution is a global or local minimum. Note that the label of each diagram...

5.) Draw Lewis dot structures for the following molecules below. Next, draw the three dimensional structure for each molecule using lines, dashes and wedges. Write what the bond angles are in each case. Calculate the difference in electronegativity (AEN) between each pair of bonding atoms. Draw dipoles for each bond in the molecule and draw a net dipole if one exists. In there is no net dipole, write "NO NET DIPOLE". Use this information to determine if the molecule is...
