MODULE 2 UNIT 3 Assignment Part C Calculate the difference in electronegativity between the atoms participating in covalent bonds for each of the following compounds. Then, select the choice corresponding to the correct structural diagrams for each. You should check the polarity of each bond and the net polarity of the molecule. If the molecule is non- polar, indicate zero for the net polarity. Each of these molecules contains a double or a triple bond. (2 marks each) a) CS 2 C 2.55 S 2.58 electonegativity is -.03 Correct diagram is iii). i) ii) iii) b) C 2 ClF or (ClCCF)
