    Okay, let me post a 5 question test for you. Each question has one star at stake (if you get a question half right, you get half-a-star, and so on.) INSTRUCTIONS: For (1) state if a GI is possible and calculate the no. of GI's, if any. For (2-3) calculate the no. of POS in the structure. |dw:1337430444045:dw| 4. State if the the following contains any plane of symmetry, and how many if any. (a) A ceiling fan (three winged) (b) A screw. 5. Will the following compound have OI's?|dw:1337430262226:dw| You have 8 minutes - TIME STARTS NOW!

    I think this will be zero - because the surrounding cyclo-propane rings are not in plane exactly, they are tilted at a some angle because there is enormous steric-repulsion from the other cyclo-propane groups. yes, I say '0'.
