Get started for freeIndole smells terrible in high concentrations but has a pleasant floral-like odor when highly diluted. Its structure is The molecule is planar, and the nitrogen is a very weak base, with \(K_{b}=2 \times 10^{-12}\). Explain how this information indicates that the indole molecule is aromatic.
An unknown organic compound is found on elemental analysis to contain $72.0 \%\( carbon, \)12.0 \%\( hydrogen, and \)16.0 \%$ oxygen by mass. It has a molecular weight of \(100 \mathrm{~g} / \mathrm{mol}\) and is slightly soluble in water. Upon careful oxidation it is converted into a ketone which contains \(73.4 \%\) carbon, \(10.3 \%\) hydrogen, and \(16.3 \%\) oxygen by mass. Indicate two or more reasonable structures for the unknown.
Give the name or condensed structural formula, as appropriate: a. (b) 2,2 -dimethylpentane (c) 4 -ethyl-1,1-dimethylcyclohexane (d) $\left(\mathrm{CH}_{3}\right)_{2} \mathrm{CHCH}_{2} \mathrm{CH}_{2} \mathrm{C}\left(\mathrm{CH}_{3}\right)_{3}$ (e) $\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}\left(\mathrm{C}_{2} \mathrm{H}_{5}\right) \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{CH}_{3}$
Indicate whether each statement is true or false. (a) The sequence of amino acids in a protein, from the amine end to the acid end, is called the primary structure of the protein. (b) Alpha helix and beta sheet structures are examples of quaternary protein structure. \((\mathbf{c})\) It is impossible for more than one protein to bind to another and make a higher order structure.
