Questions 1 and 2 refer to the four MO's of butadiene shown below. Dark shading indicates a positive sign. 0000 0000 og ogo ОО B D (I point) 1. Normally in the ground state) there are no electrons in C and 2. In the ground state, is the HOMO. (1 point) 3. Choose any four reactions. Fill in the boxes to correctly complete cach reaction. Only the first four will be graded if you answer all five. (4 points) (14.9a, 14.10b similar. 14.26b) .
