Listing 10 of 35 questions
Naphtha is a fraction obtained from petroleum (crude oil). Explain how naphtha is obtained from petroleum (crude oil). One compound in the naphtha fraction has the formula C12H26. From this formula, how can you deduce that this compound is an alkane? The alkane, C12H26, can be cracked to form an alkene that has six carbon atoms per molecule. Construct the equation for this reaction. Ethene, C2H4, can be made by cracking hydrocarbons. Draw a ‘dot-and-cross’ diagram for ethene. You only need to show the outer shell electrons. Chlorine reacts with both ethene and ethane. One molecule of ethene reacts with one molecule of chlorine. Draw the structure of the product of this reaction. Show all of the atoms and all of the bonds. One molecule of ethane can react with two molecules of chlorine. What is the molecular formula of the organic product of this reaction?
