structural Model Activity 1: Isomers: Alkanes and Substituted Alkanes Dbtain a molecular model kit and use the model kit to follow the structural exercise described below. raw the expanded structural formulas in the box provided, and name each molecule below the tructure. Provide answers to the questions in the spaces provided to the right of each structure. Note: The structure number on the report sheet may not coincide with the question number belowt Follow the structure numbers and questions. You may work in pairs for this exercise, but each student must submit their own answer sheet. 1. Make a model of CH4 (structure 1). 2. Convert methane to the alkyl halide, CH3Cl, by replacing one hydrogen atom with a chlorine atom. (structure 2) and name it. a. Did it matter which of the 4 hydrogens were replaced? b. Are all hydrogens of methane equivalent? 3. Convert your methyl chloride model to dichloromethane (structure 3). a. Did it matter which hydrogen you replaced with the second chlorine atom? b. Are the two hydrogens of dichloromethane equivalent? 4. Build a model of C2H6 (structure 4) or CH3CH3 (condensed structural formula). a. Are the six hydrogens equivalent? (hint: think about the atom replacement test) 5. Replace a hydrogen of ethane with a chlorine atom and name the new molecule, CH3CH2Cl (structure 5). a. Are the 5 hydrogens of chloroethane equivalent? Explain. 6. Add a second chlorine atom to the molecule from 5 by replacing another hydrogen atom. There are two possible isomers with the same formula C2H4Cl2 (structures 6 and 7 ); draw and name both. a. What are the condensed structural formulas for each isomer? b. Describe the structural difference between each isomer. 7. Build a model of C3H8 (structure 8 ) and name it. a. Does propane have any possible isomers that are only saturated hydrocarbons? b. If so, draw it. 8. Convert propane to chloropropane, C3H,Cl (structure 9) and make a second model of C3H7Cl that is an isomer of structure 9 (structure 10). a. Describe the structural difference between the two structures 9&10. b. Is a third isomer possible? If so, draw it. 9. Butane has a molecular formula of C.H10; build a model for the two possible butane isomers (structures 11 and 12). 10. Using your models from the previous question, determine the number of isomers with the formula C4H9Cl, and draw clear expanded structural formulas for all isomers of chlorobutane (structures 13a,b,c,d ). Attempt to name each isomer
