The antibiotic thiarubin-A was discovered by studying the feeding habits of wild

      chimpanzees in Tanzania. The structure for thiarubin-A is

1. Complete the Lewis structure showing all lone pairs of electrons.
2. Indicate the hybrid orbitals used by the carbon and sulfur atoms in thiarubin-A.
3. How many σ and π bonds are present in this molecule?

 

To describe the bonds in SF_2 using valence bond theory and to review other bonding concepts. A. Draws the Lewis structure for SF_2. B. Draw the three dimensional structure of the molecule, showing bonds and lone pairs with the appropriate bond angles. C. Name the (a) electron arrangement (geometry), (b) molecular geometry of SF_2, (c) provide the F-S-F bond angle, and (d) state whether the molecule is polar or nonpolar. (a) (b) (c) (d) D. Draw the hybrid orbitals of sulfur with the appropriate bond angle. E. How many of the hybrid orbitals will "house lone pairs?" Draw these lone pairs into your hybrid orbitals. F. Write the electron configuration of F. G. What orbital of F has only one valence electron in it? Draw this orbital of fluorine overlapping with the hybrid orbital drawn in question 5. Be prepared to show this structure to me.
