90. alkanes are a class of molecules that have the
general formula c h7+2, where n is an integer
(whole number). the table below gives the boil-
ing points for the first five alkanes with an odd
number of carbon atoms. using the table, con-
struct a graph with number of carbon atoms on
the x-axis.

a. what are the approximate boiling points for
the c2, c, cg, and cg alkanes?
b. which of these nine alkanes are gases at room
temperature (20°c)?
c. how many of these nine alkanes are liquids at
350 k?
d. what is the approximate increase in boiling
point per additional carbon atom in these
alkanes?
