Question

The tsetse fly Glossina morsitans is a large biting fly found
in regions of Africa. They carry sleeping sickness, a deadly
disease caused by a parasitic protozoan. The pheromone
secreted by the tsetse fly contains four straight-chain alkanes:
2-methylheptadecane (C18H38), 17,21-dimethylheptatriacontane (C39H80), 15,19-dimethylheptatriacontane (C39H80), and
15,19,23-trimethylheptatriacontane (C40H82). Because this
pheromone works by smell over long distances, it has proved
useful as an agent to control tsetse fly populations.
a. Draw the line formula for each of these alkanes.
b. Calculate the molar mass of each of these alkanes.
