Create Newman projections depicting conformations along the carbon-carbon bond described above in the lowest energy staggered conformation, gauche conformation, and highest energy eclipsed conformation. Appropriately label these conformations Please draw each out separately and do not just draw arrows on the molecule. OH HO HO. ОН ОН

Butane is an unbranched alkane with the condensed structure CH,CH,CH,CH,. Draw the complete structure of butane. Show all hydrogen atoms. Select Draw Rings More C H Draw the skeletal structure of butane in line-bond (line-angle) mode. Do not show hydrogen atoms. Select Draw Rings More C

For each of tthe following structural formulas, provide the indicated number of resonance structures. Use curved arrows to show the electron movement between each structure, use double headed arrow to separate the structures, and enclose all of them in a single set of brackets

5) 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.

. Consider the two methyl groups indicated with letters in the following molecular model. A: axial B: axial A: axial B: equatorial A: equatorial B: axial OA: equatorial B: equatorial

The energy difference between a tert-butyl group going from equatorial to axial in a cyclohexane is 18.3 kJ/mol. When two of the carbon atoms are replaced with oxygen atoms (molecule B) the energy difference between the two chair conformations drops to 5.9 kJ/mol. Explain this difference. (Hint: Consider what makes putting groups axial unfavorable).

Please don't provide handwritten solution ......
