Question 1 Report

Which of the following is not a direct petroleum product?
Answer Details
Methane, Ethanol, Petrol, Kerosene are all direct petroleum products as they are obtained directly from the refining of crude oil. Vaseline, on the other hand, is not a direct petroleum product. It is produced from petroleum jelly, which is a semi-solid mixture of hydrocarbons obtained from petroleum. Vaseline is obtained from petroleum jelly through a refining process that removes impurities and increases its purity. Thus, Vaseline is a derivative of petroleum, but not a direct petroleum product.
