Challenge A gas occupies 0.67 L at 350 K. What temperature is required to reduce the volume by 45%?
CEM 141 Lecture 28: Lewis Structures Part 2 Dr. Jian Hu November 9 , 2016 Bonding in Hydrocarbons Deduce the formula for a linear hydrocarbon with 7 carbon atoms (a linear hydrocarbon is a structure with only hydrogen and carbon, and is not a ring structure, or does not contain triple bonds) Answer C H 7 16 This is because each carbon on the end of the chain can be surrounded by 3 hydrogens, and each carbon in the middle of the chain can be surrounded by only 2, totaling 16 The generic formula for the numbers of carbons and hydrogens in a hydrocarbon: C n 2n+2 If a hydrocarbon does not satisfy this formula, it likely has double bonding Example: C 2 4Ethylene) each carbon is sp hybridized, a double bond exist
