AmbienTM is a sedative used in the treatment of insomnia. It was discovered in 1982 and brought to market in 1992 (it takes a long time for new drugs to undergo the extensive testing required to receive approval from the Food and Drug Administration). Identify the hybridization state and geometry of each carbon atom in the structure of this compound:Write the carbon atom(s) in numerical order as a comma separated list (e.g. to identify carbon atoms 1, 3, 4, 5, 18 and 19 write "1,3-5,18-19"). If there are no carbons with the specified hybridization, write "0" for carbon atom(s) and select "N/A" for the geometry.
