In proteins, the hydrogen bonding responsible for the secondary structure of a protein generally takes place between backbone carbonyl oxygen atoms and amide hydrogen atoms. In contrast, the hydrogen bonding that contributes to tertiary structure generally occurs between amino acid side chains.Two serine residues are shown below, with possible hydrogen bonds shown in green. Which bonds depict the hydrogen bonding that occurs between serine residues and contributes to tertiary structure?
Is there hydrogen bonding in C6H5-NH2 (Aniline)? If yes, draw two molecules of the compound and use dotted lines to show the hydrogwn bond between the two molecules and include the un-bonded pairs of electrons. If no, explain why.
4. Now draw Lewis structures of a single ethanol molecule completely surrounded by water molecules. Be sure to show hydrogen bonding (where possible) between ethanol and nearby water molecules, plus hydrogen bonding between water molecules themselves.
2. Explain why broad absorbances are expected for compounds c functional groups. Draw the hydrogen bonding interaction between two ethanol molecules ces are expected for compounds containing alcohol and carboxylic acid
2. a. Draw three water molecules interacting with each other. Indicate hydrogen-bonding with dashed lines. Show lone pairs! b. Draw two water molecules interacting with a methanol (CH3OH) molecule through hydrogen-bonding.
11) (4 pts) Shown below is a representation of hydrogen bonding between two pairs of molecules as dashed lines. For each pair, clearly indicate which of the molecules are acting as hydrogen bond donors and which are acting as hydrogen bond acceptors. ALSO, label each of the four structures as polar protic or polar aprotic. CH3 .y: CHE H"HO
13) Hydrogen bonding will not occur in molecules that contain only bonds between hydrogen and a) fluorine. b) oxygen. c) bromine. d) nitrogen. 14) Alcohol is soluble in water due to a) Covalent bond
O ADVANCED MATERIAL Identifying hydrogen-bonding interactions between molecules Lauren For each compound in the table below, decide whether there would be any hydrogen-bonding force between molecules of the compound, or between molecules of the compound and molecules of water. compound hydrogen-bonding force name formula or Lewis structure Between molecules of the compound? Between molecules of the compound and molecules of water? H dimethyl ether H - C- 0- O yes C HH HH N-chloromethylamine H-C-N- CI: yes no H. dichloromethane...
