What is optical isomerism? What do you look for to de-termine whether an organic compound exhibits optical isomerism? 1-bromo-l-chloroethane is optically active, whereas l-bromo-2-chloroethane is not optically active. Explain.
Answer to relevant QuestionsWhich of the amino acids in Fig. contain more than one chiral carbon atom? Draw the structures of these amino acids, and indicate all chiral carbon atoms. Tautomers are molecules that differ in the position of a hydrogen atom. A tautomeric fonn of thymine has the structure If this tautomer, rather than the stable form of thymine, were present in a strand of DNA during ...Consider the reaction to produce the ester methyl acetate: When this reaction is carried our with CH3OH contain¬ing radioactive oxygen-18, the water produced does not contain oxygen-18. Explain the results of this ...Consider the following five compounds. a. CH3CH2CH2CH2CH3 b. c. CH3CH2CH2CH2CH2CH3 d. e. The boiling points of these five compounds are 9.5°C, 36°C, 69°C, 76°C, and 117°C. Which compound boils at 36°C? Explain. The isoelectric point of an amino acid is the pH at which the molecule has no net charge. For glycine, that would be the pH at which virtually all glycine molecules are in the form +H3NCH2CO2-. If we assume that the ...
