A pair of theoretical enantiomers is named below. For each stereoisomer, draw the structure. Be sure to specify the stereochemistry via wedge-and-dash bonds.
(S)-5,5-dibromo-3-fluoro-2-methyl-3-hexanol
and
(R)-5,5-dibromo-3-fluoro-2-methyl-3-hexanol
Determine value for the rate of formation of HCl during the same interval of 3 seconds If the rate of disappearance H2 = -0.13 M/s at this specific time?
Meaning, use and calculation of empirical formulas, In this introduction are given the explanation of how to find out an empirical formula if one has found out the chemical elements of an unknown substance and measured their ratio of masses
Give the shape of each molecule in problem and describe whether each molecule is polar or non polar and tell whether each is soluble or insoluble in water
Recrystallization from 95% ethanol gave yellow crystals. What is the overall mechanism for this reaction including all arrows, the identification of the electrophile and nucleophile, and all charges?
Iodine does not have a permanent dipole and is therefore a non-polar molecule. Why Iodine does not have a permanent dipole a) electronegativities of two iodine atoms are identical b) two iodine atoms will cause partial charge separation
How many L of N2 gas are produced at STP when the airbag inflates if the airbag contains 132g of sodium nitride?
If a buffer solution is 0.220 M in a weak acid (Ka = 8.5 × 10-5) and 0.550 M in its conjugate base, what is the pH
Let's say that you are given a 0.215g of unknown weak acid and asked to dilute with 75 mL of DI water. You then use a standardized 0.125 M NaOH to titrate the unknown acid solution
What must the concentration be, of each member of the buffering acid/base pair, if the reaction is expected to release 0.1 millimoles of H+?
In an insulated container, a hot piece of iron (cp =0.4513 J/g-C) at 1490. C was added to 200. g of water (cp =4.184 J/g-C) at 20. C. The temperature of the resulting mixture became 90. C. What mass of iron was present?
The freezing-point depression measurement of benzoic acid in acetone yields a molar mass of 122 g; the same measurement in benzene gives a value of 242 g
Why does the 13C NMR show five different types of carbon atoms when the molecular formula indicates the compound contains seven carbon atoms
