1. What changes in color occur when bromine reacts with an alkene?

What is the overall % yield of triphenylmethane from benzophenone given the percentage yield of each step of the reaction sequence as follows? Give only two significant digits. If the answer is a whole number with two digits, do not include the decimal. 66% 70% 62% benzophenone → benzopinacol → benzopinacolone triphenylmethane Answer:

7. The reaction of methoxide anion with bromoethane to yield the ether ethyl methyl ether and the bromide anon (Br-) is an excellent example of a general reaction type called Sy2 (substitution nucleophilic bimolecular): CH,0+ CH,СH-Br a CH3-0-CH,СH; + Br- a. Change in enthalpy is -103 kJ/mol; the change in entropy is + 0.025 kJ/mol-K. Calculate DG at 300K. b. Is the reaction endergonic or exergonic? c. Is the reaction endothermic or exothermic? d. Use curved arrows to show the complete mechanism. Reaction of 2-methyl-1-butene with H-Cl could yield TWO alkyl chloride products. Draw and name 8. them.

Illustrate how diazomethane and ozone can both behave as 1,3-dipoles. Indicate, by drawing their resonance forms, how they can do so and draw the products of their reaction with styrene
