Question 88

One molecule of nonane, C9H20\text{C}_9\text{H}_{20}C9​H20​, can be cracked to produce two molecules of ethene, C2H4\text{C}_2\text{H}_4C2​H4​, and one molecule of product Y.

C9H20→2C2H4+product Y \text{C}_9\text{H}_{20} \rightarrow 2\text{C}_2\text{H}_4 + \text{product Y} C9​H20​→2C2​H4​+product Y

What is the formula of product Y?

A

C5H10\text{C}_5\text{H}_{10}C5​H10​

B

C5H12\text{C}_5\text{H}_{12}C5​H12​

C

C7H14\text{C}_7\text{H}_{14}C7​H14​

D

C7H16\text{C}_7\text{H}_{16}C7​H16​
