1) A Grignard reagent is an organomagnesium halide (or R-Mg-X). Explain the difference in the reactivity of the carbon bonded to the halide in an alkyl halide (R-X) versus the carbon bonded to the magnesium in a Grignard reagent.
2) Grignard reactions require a solvent such as diethyl ether. Please explain what the purpose of the solvent is besides dissolving the reagents. (Hint: What specific purpose does diethyl ether have in the formation of the Grignard reagent?)
What is the de Broglie wavelength of a 145 g baseball traveling at 30.0 m/s (67.1mph)? Is the wavelength much larger or smaller than the diameter of an atom .
the reaction mechanisms could be coupled, how many moles of ATP will be needed to drive
predict the formula of a compound that presumably would result from the reaction between magnesium and topaline, and name the compound.
How many kilojoules of heat are required to melt a 10.0-g popsicle at 0 C? Assume the popsicle has the same molar mass and heat of fusion as water.
A 5.00 L flask at 279 K contains a mixture of He and O2 with a total pressure of 1.00 atm. If the mole fraction of O2 is 0.40, what is the mass fraction of O2?
Suppose you were asked to carry out an aldol condensation reaction between benzaldehyde and 5-methylhexanal,
Microwave ovens use microwave radiation to heat food. The microwaves are absorbed by moisture in the food, which is transferred to other components of the food. As the water becomes hotter
Determine the boiling point of a 1.5m aqueous solution of fructose.
If the 53 g aluminum block is initially at 25^circ C, what is the final temperature of the block after the evaporation of the 1.02 galcohol? Assume that the heat required for the vaporization of the alcohol comes only from the aluminum block and t..
