a) To determine boiling point of liquids, we need to look at both intramolecular and intermolecular forces of attraction. Name the intra- and inter-molecular forces in the following liquids. INTRA-MOLECULAR INTER-MOLECULAR MOLECULE a. Trichloromethane, CHCI b. Ethanol, CH,CCHOH c. Water, HO ii. FORCES FORCES Arrange the above compounds in the order of INCREASING boiling points. Justify your answer. (3+3 marks) b) Sulphate ion, SO is used widely in the formation of sodium laureth sulfate, SLES, a common detergent in shampoo formulations. i. Draw the MOST STABLE Lewis structure of SO ili. Calculate the formal charge of each atom to prove its stability. (2+2 marks)
