Draw the Lewis structure of acetone, CH3COCH3 and chloroform, CHCl3 using correct bond angle relationships; include partial charges on each atom (if any). Show how these two molecules position themselves when next to each other and show the attraction using a dotted line. Answer questions→ a) List the primary and secondary intermolecular forces (in the order of significance or strength) in acetone: ________________ , _________________ b) Is acetone a polar or nonpolar molecule? _______________ , c) Which is more polar, acetone or chloroform? ________________ . d) Do you predict the ∆Hsln for mixing acetone with chloroform to be positive (>0), negative (<0) or close to zero (ideal solution)? Explain why.
