Question

#Hattenthecurve #lattenyourmarks 4 1. Consider ethylene C,H, which has a Ded symmetry group. We now want to change the symmetry group by cutting it in half (through the double bond) and substituting one half by a molecular fragment. C2H, CH? Find a substituent molecular fragment with less or equal to 6 atoms such that the symmetry group of the new molecule has the following symmetry groups as denoted in (a), (b) and (c)! You can be creative, but keep it simple (use 6 or less atoms), and make sure that your resulting molecules follow all rules of chemical bonding. Include a sketch to illustrate your answer. Write down impossible if it is impossible to find a suitable molecular fragment and explain why it is impossible. (a) D24 (c) C (d) For each of your designed molecules, put down iſ the molecule can be polar or not.
