Intermolecular Forces Practice
For each of the following compounds, determine the main intermolecular force. You
may find it useful to draw Lewis structures for some of these molecules:
1)
nitrogen gas ________________________________
2)
carbon tetrachloride ________________________________
3)
H2S ________________________________
4)
sulfur monoxide ________________________________
5)
N2H2 ________________________________
6)
boron trihydride ________________________________
7)
CH4O ________________________________
8)
9)
SiH2O ________________________________
Explain why ethyl alcohol (C2H5OH) has a higher boiling point (78.40 C) than
methyl alcohol (CH3OH; 64.70 C).

Rank the following by from lowest to highest anticipated boiling point: C2H4, CH4,
Ne, H3COCH3.

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(CH2OH)2.
