Which type of intermolecular force accounts for each of these differences? (a) Acetone, (CH3),CO, boils at 56C; dimethyl sulfoxide or DMSO, (CH) SO, boils at 189C. (b) CC1 is alliquid at atmospheric pressure and room temperature, whereas CH is a gas under the same conditions. (c) HO boils at 100C but HS boils at -60C. (d) 1-propanol (CH3CHCHOH) boils at 97C, whereas 2-propanol 2 2 (CHCH (OH)CH) boils at 82.6C. HC CCH CH 3 Acetone H3C S CH3 DMSO
