Question

On what factor does the rate of oxidation of a hydrocarbon molecule depend?

(a) On the calorific value of the compound

(b) On the number of carbon atoms

(c) On the rate of combustion

(d) On its moisture content

I had been asked this question during an internship interview.

The above asked question is from Knocking topic in division Fuels and Combustion of Engineering Chemistry II

Answer 1

Right answer is (b) On the number of carbon atoms

For explanation I would say: The rate of oxidation of a hydrocarbon molecule depends on the number of carbon atoms in the molecule, on the structure and on the temperature. The rate of oxidation should be moderate.
