State and compare the four models of chbrici

Reference no: EM13194144

Part A.

1. For the molecules CH4, NH3, and H2O, what conclusions can you make concerning the H-X-H bond angle and the number of unshared (lone) pairs of electrons around the central atom X?

2. What conclusions can you make concerning the size of the central atom X and the X-H bond length?

Part B

3. Consider O3 and NO3-. Look at the O-O and N-O bond lengths within each molecule. Are they the same or different? Use resonance structures to explain your observations.

Part C.

1. Compare the four models of CHBrICI. Are they all the same (superimposable on each other? If the answer is yes, can you construct any that are not the same?

2. If you were able to construct models that were superimposable, draw them in your lab notebook. What is the relationship between the two models, if any? In other words, how do they resemble one another?

3. If you generated non-superimposable models, do you expect your molecules to have different physical properties? Why or why not?
