Concept explainers
Interpretation:
Why the nonpolar
Concept introduction:
The boiling point of a compound depends on the strength of the intermolecular forces that exist between its molecules. The main types of intermolecular interactions in increasing order of strength are induced dipole-induced dipole, dipole-dipole, and hydrogen bonding.
Polar molecules have both induced dipole-induced dipole interactions, and possibly hydrogen bonding too. Nonpolar molecules have only induced dipole-induced dipole interactions. Generally nonpolar molecules have weaker intermolecular interactions than polar molecules of comparable size.

- Which molecule in the following pair would you expect to have the highest boiling point? H.arrow_forwardBranching of the hydrocarbon chain lowers the boiling points of the lower homologous series, such as the hydrocarbons and alcohols. Therefore, an assumption can be made that branching lowers the forces attraction in these molecules.arrow_forwardProblem: (a) Draw six (6) constitutional isomers of C6H1202. (b) Which of the compounds you drew would be the most soluble in water? Explain your choice. (c) Which of the compounds you drew would be the most soluble in hexane? Explain your choice.arrow_forward
- How conformational change involves ring-flipping ?arrow_forwardInterconversion of the staggered and eclipsed conformations of alkanes requires rotation around a -C bond such as the one depicted below (see arrow). Using your knowledge of bonding, explain why these rotations do not significantly affect the energy (strength) of these bonds. You may find it helpful to describe the type of bond being rotated.arrow_forward9) Synthesize the molecule on the right, beginning with the molecule on the left. Br H OH H Brarrow_forward
- (b) Glucose has the following structure. Describe the properties based on the structure of glucose.arrow_forwardCircle all of the chiral centers (i.e., asymmetric carbon atoms) in the following compounds.arrow_forward5) Provide your own list of alkanes. They can not be the same structure but should all have the same number of carbons. (see the problem solving video for an example) Rank them in order of increasing melting point. You can not have the same example as someone else.arrow_forward
- In each pair of compounds, which compound has a higher boiling point? Explain your reasoning.(a) octane or 2,2,3-trimethylpentanearrow_forwardLook at the model of chloroethane. a) Do all chloroethane molecules spend all of their time in this preferred conformation? Explain why or why not. b) What is the preferred conformation called?arrow_forwardFor which isomer would you expect a greater equilibrium percentage of molecules with the alkyl group in the axial position, explain.arrow_forward
