Unformatted text preview: and least stable? __________________________________________ D. (3pts) explain your choice for the most stable (one or two sentences): 5 Name:________________________________________________ A. 4pts. In formaldehyde, H2C=O, describe the hybridization of C and O. Carbon:_________________ Oxygen:__________________ B. 6pts. Draw the molecule and the orbital picture showing all bonding interactions and lone pairs in their respective orbitals. Label all σ and π bonds. 6 Name:________________________________________________ A. Consider the following: the 1,3 ­diaxial strain from each H to Br interaction is 0.3 kcal/mol, and for H to CH3 is 0.9 kcal/mol. Draw the most stable conformation of the structures below (3pts each), do a ring flip and draw the resulting higher energy structure (3pts each), calculate the strain energy of the highest energy structure (2pts each). Br Br Most stable Ring flip Strain Energy Strain energy B. 2pts. Of the two molecules above, give the name of the most polar compound.
