Answer 2

Cetane molecule considered for calculating the cetane number.

• Cetane number is percentage of cetane [CH₃-(CH₂)₁₄-CH₃], in a mixture of cetane and 1-methyl naphthalene, that gives the same values in property with the actual fuel.
• So, it is clear that the cetane number is calculated on the basis of the cetane molecule. Rest of the compounds are not the primary substance that is considered in this case.
• That's why, cetane molecule will be the correct answers of this question.
