Specific compounds are named in the boxes below and the functional group part of the name is in boldface. For each boldface functional group, draw an expanded structural formula. Indicate the approximate wavenumbers of the IR absorption peaks that could be used to distinguish between the members of each of the pairs of compounds in a row. Mention at least one distinguishing absorption peak for each compound in the pair that is absent in the spectrum of the other compound (except for the compound in the lower right box). Example: acetonitrile and methylamine -C?N -NH2 (primary amine) Nitriles have a CN triple bond stretch at ~2250 cm-1; sharp Primary amines have an NH stretch around 3500-3300 cm-1 that appears as two bands (the CN single bond stretch at 1350-1000 cm-1 is weak and difficult to distinguish). A. 1-propanol B methyl ethyl ether C. 1-pentyne D 1,3-pentadiene E. pentanal F 2-pentanone WIll paypal the first answer correctly given:)
Calculate the entropy of unfolding of lysozyme at 25 oC, given that the difference in PCof unfolding is 6.28 kJ/mol/K at both 25 oC and 75 oC. Hint: consider a path of 25 oC (folded)?75.5 oC(folded) ?75.5 oC(unfolded) ?25 oC(unfolded).
HF is a stronger acid than HBR because F has greater electronegativity than Br 2) the acid (HA) strength will increase when the H-A bond strength increases
Lanthanum has two naturally occuring isotopes. 0.089% of lanthanum atoms are 138La and the rest are 139La. Estimate the average atomic mass of lanthanum, to the nearest tenth of an atomic mass unit.
The fat, tripalmitin, when hydrolyzed with aqueous NaOH followed by acidification with HCl yields glycerol and palmitic acid.
