We could have used the trend of lower atomic molar mass having a lower boiling point on Q1 and Q2 only if it states that answers C and D are n-ceC5H12 and n-ceC4H10 respectively or i-ceC5H12 and i-ceC4H10 respectively. In view of the insufficiency of information about the reasons of self-oscillations it is necessary to determine the gas-dynamic physical and chemical parameters that cause oscillations of the heat release rate in the vortex combustion chambers.

Neopentane is almost spherical with a small surface area for intermolecular interactions whereas n -pentane has an extended conformation that enables it to come into close contact with other n -pentane molecules.
