Question 26

One molecule of dodecane, C12H26\text{C}_{12}\text{H}_{26}C12​H26​, is cracked to produce two molecules of ethene, C2H4\text{C}_2\text{H}_4C2​H4​, and one molecule of product Y.

C12H26→2C2H4+product Y \text{C}_{12}\text{H}_{26} \rightarrow 2\text{C}_2\text{H}_4 + \text{product Y} C12​H26​→2C2​H4​+product Y

What is the formula of product Y?

A

C8H16\text{C}_8\text{H}_{16}C8​H16​

B

C8H18\text{C}_8\text{H}_{18}C8​H18​

C

C10H22\text{C}_{10}\text{H}_{22}C10​H22​

D

C10H18\text{C}_{10}\text{H}_{18}C10​H18​
