The reaction of 1,3-butadiene with HCI produces two addition products. (See below) H-CI CH CH CH-CH3 CH, CH=CH-CH3 + CHCH-CH=CH2 I II The relative amounts of the products that form is strongly temperature dependent. Here are the results: At 0°C, the following product composition is observed: product I (71%), product II (29%). At 42°C, the following product composition is observed: product I (15%), product II (85%). ANSWER THE FOLLOWING QUESTION: Why does the addition product I predominate at the lower temperature (0°C)? Select one: Product I predominates at lower temperature because it has more t а. electron delocalization than product II. O b. At lower temperature, the reaction is equilibrium controlled: product II is more stable than product I, so product Il predominates. Product I is less sterically hindered, so it predominates. С. d. At lower temperature, the reaction is kinetically controlled: product I forms faster, so product I predominates.

5:12 Mon, Oct 2 tv Document Sharing User Settings ⠀⠀⠀ In nature, one common strategy to make thermodynamically unfavorable reactions proceed is to couple them chemically to reactions that are thermodynamically favorable. As long as the overall reaction is thermodynamically favorable, even the unfavorable reaction will proceed. Part A Consider these hypothetical chemical reactions: AG = 10.1 kJ/mol 1. A = B, 2.
