Concept explainers
(a)
Interpretation:
Theglycine amino acid needs to be classified as non-polar or polar. If it is polar then the R group needs to be classified as neutral, acidic or basic. Also, if it is hydrophobic or hydrophilic needs to be identified.
Concept Introduction :
The amino acid consists of two
(b)
Interpretation:
The threonine amino acid needs to be classified as non-polar or polar. If it is polar then the R group needs to be classified as neutral, acidic or basic. Also, if it is hydrophobic or hydrophilic needs to be identified.
Concept Introduction :
The amino acid consists of two functional groups that is amino group as well as carboxylic acid group. There are 20 essential amino acids which are different from each other due to the different R group attached to the carbon containing amino as well as carboxyl groups.
(c)
Interpretation:
The phenylalanine amino acid needs to be classified as non-polar or polar. If it is polar then the R group needs to be classified as neutral, acidic or basic. Also, if it is hydrophobic or hydrophilic needs to be identified.
Concept Introduction :

- For each reaction shown below follow the curved arrows to complete each equationby showing the structure of the products. Identify the acid, the base, the conjugated acid andconjugated base. Consutl the pKa table and choose the direciton theequilibrium goes. However show the curved arrows. Please explain if possible.arrow_forwardA molecule shows peaks at 1379, 1327, 1249, 739 cm-1. Draw a diagram of the energy levels for such a molecule. Draw arrows for the possible transitions that could occur for the molecule. In the diagram imagine exciting an electron, what are its various options for getting back to the ground state? What process would promote radiation less decay? What do you expect for the lifetime of an electron in the T1 state? Why is phosphorescence emission weak in most substances? What could you do to a sample to enhance the likelihood that phosphorescence would occur over radiationless decay?arrow_forwardRank the indicated C—C bonds in increasing order of bond length. Explain as why to the difference.arrow_forward
- The SN 1 mechanism starts with the rate-determining step which is the dissociation of the alkyl halide into a carbocation and a halide ion. The next step is the rapid reaction of the carbocation intermediate with the nucleophile; this step completes the nucleophilic substitution stage. The step that follows the nucleophilic substitution is a fast acid-base reaction. The nucleophile now acts as a base to remove the proton from the oxonium ion from the previous step, to give the observed product. Draw a curved arrow mechanism for the reaction, adding steps as necessary. Be sure to include all nonzero formal charges.
