1) For an aldol reaction, the key step is the attack on the partially positive carbonyl carbon by a nucleophile. Rank benzaldehydes by their reactivity in an aldol reaction.
2) why doesn't this aldol reaction make multiple major products even though there are two carbonyl compounds in the reaction?
3) why do you only obtain the trans isomer as the product for these reactions?
In an oxidation-reduction reaction, it required 25.6 ml of a 0.65 M potassium permanganate solution to reach the equivalence point with 15.0 mL of an iron(II) sulfate solution.
If a raindrop weighs 57 mg on average and 5.1 X 10^5 raindrops fall on a lawn every minute, what mass of rain falls (in kg) on the lawn in 1.5 hours?
If a total of 13.5 mol of NaHCO and 4.5 mol of C H O react, how many moles of CO and Na C H O will be produced? 3NaHCO (aq) + C H O (aq) 3CO (g) + 3H O(s) +Na C H O (aq).
One mole of an ideal gas with Cv,m = 3R/2 initially at 325K and 1.5*10^5 Pa undergoes a reversible adiabatic compression. At the end of the process, the pressure is 2.50 * 10^6 Pa.
Consider the following exothermic reaction: C2H4 (g) + Cl2 (g) C2H4Cl2 (g) If you were a chemist trying to maximize the amount of C2H4Cl2 produced, which of the following might you try?
draw the Lewis structure with all bonds and lone pairs (b) indicate directions in all bond dipoles (c) indicate the molecular dipoles and (d) indicate the shape of each molecule.
A 10.4-g sample of CaCl2 is dissolved in 107 g of water, with both substances at 25.0°C. Calculate the final temperature of the solution assuming no heat lost to the surroundings and assuming the solution has a specific heat capacity of 4.18 J/°C ..
Calculate the change in pH when 5.00 mL of .100 M HCL is added to 100 mL of a buffer solution
Calculate the pressures in the flask in parts a and b (in torr) if the atmospheric pressure were instead 675 torr.
