Question

The table shown here lists the molar heats of vaporization
for several organic compounds. Use specific examples from
this list to illustrate how the heat of vaporization varies
with (a) molar mass, (b) molecular shape, (c) molecular
polarity, (d) hydrogen-bonding interactions. Explain these
comparisons in terms of the nature of the intermolecular
forces at work. (You may find it helpful to draw out the
structural formula for each compound.)
