(1) describe in detail reagent solvent you can employ to prepare OTTO DIELS and KURT ALDER reaction. Note that this reaction involves the 1-4- addition of a conjugated diene in S-cis, S-trans conformation to an alkene in which two new sigma bond are formed from two (pi) bond
(2) Make a table showing the gram quantities, and mole quantities of each reagent required in the Diels Alder reaction of methyl vinyl ketone with 1,3- butadiene, and higher concentration of endo and exo isomers, and including cis Norbornene-5,6- endo dicarboxylic Anhydride
(3) Outline the steps required for this synthesis
In climates where snow and ice cover roads in winter, some agencies spread solid ice melter on the road. suggest and identify for the ice melter and briefly explain how it works.
Propanoic acid has Ka of 1.4x10^-5. If we make a solution 0.100M propanoic acid, what concentration of sodium propanoate should be added to give a buffer with a pH of 5.0?
2 NH3(g) + 3 O2(g) + 2 CH4(g) → 2 HCN(g) + 6 H2O(g) If 5.08 103 kg each of NH3, O2, and CH4 are reacted, what mass of HCN and of H2O will be produced, assuming 100% yield?
Calculate: a. kg of pressed beans from stage 1 b. kg of extracted meal from stage 2 c. kg of final meal & wt% protein of it ans: 8723 kg, 8241 kg, & 7816 kg and 44.8 wt% protein.
Restricting yourself to straight-chain (unbranched) compounds, draw the structures of the possible constitutional isomers of pentene. There are two "variables" -- the position of the double bond; and cis/trans isomerization at that double bond.
Which of the following is correct? A) Solubility is the concentration of unsaturated ions in solution. B) Ksp is the same as the solubility. C) Ksp is an equilibrium constant and solubility is the concentration of a saturated solution
The intial temp of the water is 19.0C and the final temp of the system is 25.1C. The heat loss to calorimeter is negligible. What is the mass of the water?
