Two stereoisomers of a bromodecalin are shown. Although the difference between these stereoisomers may seem trivial, one isomer undergoes elimination with KOH much faster than the other. Predict the products of these eliminations, and explain the large difference in the ease of elimination.
Suppose the normal freezing point of cyclohexane is 6.55 C. While 0.458 g of benzophenone is dissolved in 15.0 g of cyclohexane, the freezing point is found to be 3.19 C. Explain what is the experimental molar mass of benzophenone. Kf cyclohexane ..
The hydrogen gas formed in a chemical reaction is collected over water at 30 at a total pressure of 727 .What is the partial pressure of the hydrogen gas collected in this way
Assume a bowl of 600 g of water is placed in a microwave oven that puts out 888 watts (J/s). How long would it take in seconds to raise the temperature of the water from 12.0 C to 43.1 C
Given the reactant side of the total ionic equation for the neutralization reaction of potassium hydroxide KOH with hydrochloric acid HCl, write the total ionic equation (also known as the complete ionic equation) by entering both the reactant and..
A twenty seven (27) milliwatt LASER is being used in surgery. An inexperienced physician inadvertently directs the LASER at a nearby wall that is 4.1 meters away. If the emergent beam diameter is 1.1 cm
a plot of density of ethyl alcohol as a function of temperature was found to be linear. what would you expect the value
Phenol is an enol. in water it will undergo an enol to keto tautomerization. 1. will this reaction likely go by a base or acid catalyzed mechanism. show the mechanism . 2. which is more stable the enol or the ketoform. Why
draw reaction mechanisms for the e1 and the two e2 reactions. predict the major products for these reactions based on
A titanium bicycle frame contains the same amount of titanium as a titanium cube measuring 6.6cm on a side. 1) Use the density of titanium to calculate the mass in kilograms of titanium in the frame.
Draw a reaction coordinate diagram for a one-step, exothermic reaction in which the the thermodynamic product is not the kinetic product (that is, the most stable product is the slowest to form).
Balnace the following half reactions in an acidic solution a) MnO4 -(aq)---- MnO2(s) b) IO2- (aq)----Io4-(aq) based on (a) and (b) above, write balanced redox eqautions of (A) in an acidic solution MnO4-(aq) + IO3_(aq)----MnO2(s) + IO4- (aq) (A)
Solution A is twice as concentrated as solution B but has a smaller absorbance value. Both solutions abosrb maximally at wavelength =585 nm. Give a through explanation for this observation.
