A sample of petroleum contains 30% n-heptane, 10% 2-methyl hexane and 60% 2, 2, 4-trimethyl pentane, the octane no. of this sample will be;
(1) 30% (2) 60% (3) 10% (4) 70%
Dear Student,
2,2,4-trimethylpentane is also called as iso-octane.
The octane number of iso-octane is taken as octane number of fuel.
So, 60% iso-octane will have octane number = 60%
Therefore, octane number of fuel = 60%
Hence, correct answer is (2)
