Xenon tetraoxide, XeO 4 , is a yellow crystalline solid that is stable below –36ºC. Above this temperature XeO 4 explodes to give Xe and O 2 gas. Draw the most stable Lewis structure for XeO 4 . 2. According the VSEPR theory, what are the theoretical values of the four bond angles that have been labelled in the organic structure below? Angle a: ______ Angle b: ______ Angle c: ______ Angle d: ______ 3. Draw the best Lewis structure for ICN showing the correct I–C–N angle. Include an arrow such as the ones used in your textbook to show the direction of the molecular dipole moment ( , where the arrow points towards the negative end). 4. Draw a structural formula for 3-ethyl-2,4,4-trimethyl-2-pentene 5. Suppose that we could easily add or subtract electrons from F 2 . Using the molecular orbital diagram for F 2 , what ionic form of F 2 would be
