Unformatted text preview: n 1-butene (CH3 CH2 CH CH2 ) reacts with bromine to give CH3 CH2 CHBrCH2 Br. Bond enthalpies are C H : 412 kJ/mol; C C : 348 kJ/mol; C C : 612 kJ/mol; C Br : 276 kJ/mol; Br Br : 193 kJ/mol. 1. 181 kJ/mol 2. 288 kJ/mol 3. 507 kJ/mol 4. 317 kJ/mol 5. 95 kJ/mol 024 (part 1 of 1) 10 points The heat energy released or absorbed by a chemical reaction is generally determined by the difference between 1. the energy that must be put in to break 026 (part 1 of 1) 10 points Bond energies are approximate because CH4 (g) + I2 CH3 I(g) + HI(g) . 025 (part 1 of 1) 10 points Consider the reaction 6 the bonds in the reactants and the energy that must be put in to make the bonds in the products. 2. the energy that must be put in to break the bonds in the reactants and the energy that is released upon making the bonds in the products. 3. the energy that is released upon breaking the bonds in the reactants and the energy that must be put in to mak...
