VSEPR Objective : This lab is to study the shape and polarity of molecules using VSEPR theory with emphasis on sigma bonds (Part 1) and pi bonds and resonance (Part 2) Procedures: Nothing to do before the lab. We are making the models together in class. Prelab Questions : PART 1: (PL1) Draw the Lewis dot structure of each compound (as having covalent bonds). (a) BeH2 (b) BH3 (c) GeH2 (d) CH4 (e) NH3 (f) H2O (g) PCl5 (h)...
Which of the following are conjugate acid-base pairs? (i) H3O+/H2O (ii) NH4+/NH3 (iii) H2SO4/HSO4- (iv) H2PO4-/HPO43- Select one: a. (i)(ii) (iii) b. They all are c. (ii) and (iv) d. (i) (iv)
Using your model kit, make models of each of the following molecules. Visualizing your completed model, draw a 3D formula for the molecule (use a wedge drawing, don’t attempt to draw the model pieces themselves). In molecules C- G, draw the 3D formulas using any convenient conformation*. A. CH4 B. CH2Cl2 C. CH3-CH3 D. CH3-CH2-CH3 E. CH3-CH2-Cl F. CH3-C=O G. CH3-C=CH2 | | CH3 CH3
3. Consider the four compounds CH4, NH3, H2O, and HF. Use periodic trends in bond lengths and the electronegativity table in Chang to answer the following questions: (a) Which molecule is expected to have the longest bonds? (b) Which molecule is expected to have the most polar bonds? (c) Which molecule is expected to have the least polar bonds?
