Questions 7-15 The molecule is ethane 71 2 O ACTIVITY 1.2.1 Biological Macromolecules in 3-D 7. Orient the two molecules so that portions of the mo lecules that would normally form intermolecular bonds lie next to each other. In this activity, you will build molecular models of biologically important molecules using ball-and-spring molecular model 1) What intermolecular forces help to hold these mo- building kits and then you will view these and other molecules lecules together! of interest using computer-generated...
Functional Groups In organic there are a number of combinations of atoms that commonly occur. These are called functional groups. Eventually you will see that functional groups are the basis for organic reactivity. For now, we want to learn to draw functional groups and determine if the functional groups are nonpolar, polar or can hydrogen bond to themselves or to water. Please review Appendix E, Table 2. 1. Alkanes only contain carbon and hydrogen and only have sigma bonds between...
4. Build a model of the 1,2-ethanediol molecule. a. Identify the electron-pair and molecular geometry around each carbon and oxygen atom. b. What are the bond angles for H-C-H? For H-C-C? For C-C-O? For C-O-H? c. Draw two different structures of the molecule in which the –OH groups on the two carbon atoms have different orientations with respect to each other. Which structure is more stable? Explain your reasoning (Hint: What factors contribute to the stability of a structure?). Can...
Answer the questions in the table below about the shape of the ozone (03) molecule. How many electron groups are around the central oxygen atom? Note: one "electron group" means one lone pair, one single bond, one double bond, or one triple bond. What phrase best describes the arrangement of these electron groups around the central oxygen atom? (You may need to use the scrollbar to see all the choices.) (choose one) x 6 ?

For the molecule below a) Box in all atoms that can hydrogen bond with water but not with acetone (CH3OCHS) b) Label all electrophilic carbons (use 6*) NH c) Label the least basic nitrogen. НО d) Label the most acidic hydrogen
please help The dehydration of alcohols Under acidic conditions, alcohols will undergo a dehydration reaction, producing an alkene and water. During the reaction, the hydroxyl group of the alcohol and a hydrogen atom from an adjacent carbon atom are lost. The reaction takes place in three steps, as shown in the diagram. (Figure 1) In the first step, a hydrogen lon bonds to the hydroxyl group of the alcohol. In the second step, the protonated hydroxl group leaves the compound,...
