Use the information in the table below to respond to the statements and questions that follow. Your answers should be in terms of principles of molecular structure and intermolecular forces. a) Draw the complete Lewis electron-dot diagram for ethyne in the appropriate cell in the table below. (1) Compound Ethanethiol Formula CH3CH2SH Ethane CH3CH3 Lewis Electron Dot Diagram HH H:C:C:S:H HH HH H:C:C:H HH HH H:C:C:0:H HH Ethanol CH3CH2OH Ethene CzH b) Which of the four molecules contains the shortest carbon-to-carbon bond? Explain. [2] c) Explain how the structure of the molecules affects the energy that is required to boil ethanol. Consider the statement " As ethanol boils energy goes into breaking C-C bonds, C-H bonds, C-o bonds and O-H bonds." Is the statement true or false? Justify your answer. [2] d) Ethanol is completely soluble in water, whereas ethanethiol has limited (significantly less) solubility in water. Account for the difference in solubilities between the two compounds in terms of intermolecular forces. [2]
