## Introductory Chemistry (5th Edition)

Miscibility of liquid depends on the polarity of the molecule. Among the given liquids one is polar and the other is nonpolar. Atoms in water have different electronegativities and hence it is polar. In $CH_{3}CH_{2}CH_{2}CH_{2}CH_{3}$, all the polarities in bonds cancel away making the molecule nonpolar. Hence both liquids are not miscible with one another.
