More Intermolecular Force Practice Problems 1) For each of the following compounds indicate which intermolecular force is most important: a) FCN __________________________________ b) HCN __________________________________ c) C 2 H 6 __________________________________ d) CF 2 H 2 __________________________________ 2) Explain why ethyl alcohol (C 2 H 5 OH) has a higher boiling point (78.4 0 C) than methyl alcohol (CH 3 OH; 64.7 0 C). 3) Rank the following by from lowest to highest anticipated boiling point: C 2 H 4 , CH 4 , Ne, H 3 COCH 3 . 4) Motor oil largely consists of molecules that consist of long chains of carbon atoms with hydrogen atoms attached to them. Using your knowledge of intermolecular forces, why wouldn’t it be better to use a compound like glycerol. The formula of glycerol is CHOH(CH 2 OH) 2 .
