A student adds bromine solution to a test tube containing an isomer of C3H6. After shaking the sample and exposing it to UV light, the student observes that the colour of the bromine solution changes from orange to clear. Provide a hypothesis for what happened in the test tube. What do you believe to be the structure of the original isomer,

85. Propane, C3H8, is a hydrocarbon that is commonly used as a fuel. (a) Write a balanced equation for the complete combustion of propane gas. (b) Calculate the volume of air at 25 °C and 1.00 atmosphere that is needed to completely combust 25.0 grams of propane. Assume that air is 21.0 percent O2 by volume. (Hint: We will see how to do this calculation in a later chapter on gases—for now use the information that 1.00 L of air at 25 °C and 1.00 atm contains 0.275 g of O2 per liter.) (c) The heat of combustion of propane is −2,219.2 kJ/mol. Calculate the heat of formation, ΔH∘fΔHf° of propane given that ΔH∘fΔHf° of H2O(l) = −285.8 kJ/mol and ΔH∘fΔHf° of CO2(g) = −393.5 kJ/mol. (d) Assuming that all of the heat released in burning 25.0 grams of propane is transferred to 4.00 kilograms of water, calculate the increase in temperature of the water.
Prof Adam and his colleagues synthesized compound E, with the molecular formula CSH1CI. They wanted to identify the chemical properties of this compound by conducting a series of chemical tests. Compound E produced compound F when it reacted with sodium hydroxide in the presence of water and reflux. In the presence of ultraviolet light, compound G reacts with halogen gas to form compound E. Compound E is formed when compound H undergoes addition reactions involving hydrogen chloride. When compound E reacts with aqueous ammonia in the presence of heat, compound I is formed. Draw the possible skeletal structures of compound F to I. Identify the IUPAC nomenclature of compounds F, G, H, and I.
(a) When the metallic element sodium combines with the nonmetallic element bromine, Br2(l), how can you determine the chemical formula of the product? How do you know whether the product is a solid, liquid, or gas at room temperature? Write the balanced chemical equation for the reaction. (b) When a hydrocarbon burns in air, what reactant besides the hydrocarbon is involved in the reaction? What products are formed? Write a balanced chemical equation for the combustion of benzene C6H6(l), in air.

Draw the Lewis structure of acetic acid, CH3CO2H, clearly indicating all non-bonding pairs of electrons. Even though nitrogen and phosphorus have the same number of valence electrons, nitrogen can only bond to chlorine four times forming NCl4+ but phosphorus can bond with chlorine five times forming PCl5. Explain. Draw all the isomers of C4H9Br, using bond-line formulas. Draw the Lewis structure of the nitrite ion, NO2–, clearly indicating resonance contributors as well as non-bonding pairs of electrons and formal charges, as relevant. Nitromethane is a polar molecule but contains 2 equal polar covalent bonds. Briefly explain why and draw a relevant 3-dimensional structure to show the overall dipole moment of the molecule. Draw all isomers of C6H12O that are aldehydes.
