If the temperature of a hypothermia victim is 29 .1 o C , the temperature in degree Fahrenheit has to be calculated. Concept Introduction: The tendency of the heat energy to get transferred from one object to another object.is indicated by temperature. This is measured by a device called “thermometer”. Celsius kelvin and Fahrenheit are some commonly used scales in thermometer. For example the conversion of one state of substance to other state can be measured by this thermometer. The relationship between the Fahrenheit and Celsius scales can also be stated in an equation format. o F = 9 5 ( o C ) + 32

Question

Kumada Coupling: 1. m-Diisobutylbenzene below could hypothetically be synthesized by Friedel-Crafts reaction. Write out the reaction with a mechanism and give two reasons why you would NOT get the desired product. Draw the reaction (NOT a mechanism) for a Kumada coupling to produce the molecule above from m-dichlorobenzene. Calculate the theoretical yield for the reaction in question 2 using 1.5 g of p-dichlorobenzene and 3.0 mL isobutyl bromide. What signals appeared/disappeared/shifted that indicate that you have your intended product and not starting material? What other impurities are present in your product and how do you know?
