Question #1: (4 points) Carbon bonded to 4 atoms. When carbon is bonded to 4 atoms, it adopts a tetrahedral geometry (sp3 hybridization). This geometry maximizes the distance between each of the four atoms forming single bonds with the carbon. Hydrocarbon compounds in which all of the carbons are singly bonded to 4 other atoms are called “saturated”. Examples are methane (natural gas), ethane, propane, butane and octane. Out of the 20 molecular structures, identify ethane (C 2 H 6 ) and analyze its structure. a) What is the C-C bond distance? b) What are the H-C-H and H-C-C bond angles? c) Save the structure and upload it into your laboratory report. a) The C-C bond distance is 0.154 nm. b) The H-C-H bond angle is 108.1 degree and the H-C-C bond angle is 110.8 degree. c)

Question #2: (4 points) Carbon bonded to 3 atoms. When carbon is bonded to 3 atoms, it adopts a trigonal planar geometry (sp2 hybridization). The carbon atom forms two single bonds with two atoms, and a double bond with the third. Hydrocarbon compounds that contain one or more C=C
