CH204 2018 Final Exam Question 3 (a) Discuss how the oxides of sulphur (SO 2 ) and nitrogen (NOx) play a central role in acid rain. (5 marks) (b) Carbon monoxide (CO) which is one of the oxides of carbon has a Lewis structure given below. Show the hybridization schemes in C and O and sketch how the orbitals overlap to form the 3 bonds and the lone pairs. (5 marks) (c) Fluorine is the most reactive element in the periodic table. However, it can only exhibit the -1 oxidation state. Explain why the heavier halogens do exhibit more than one oxidation state but not fluorine. Illustrate by using the box and arrow diagram. (3 marks) (d) Given below is the valence electronic structure for iodine in the inter-halogen compound, IF 5 . Show how this electronic structure changes during hybridization and indicate what the hybridization scheme is. Name the geometry and the shape of the compound. (4 marks) (e) Draw the structures of OBr 2 , OCl 2 , OF 2 and arrange them in the order of increasing bond angle <X O X, (where X=F, Cl and Br). Briefly mention the reason for the order given.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
