Question 130

Which process has the highest atom economy for preparing propene, C3H6\text{C}_3\text{H}_6C3​H6​?

In each process, assume that propene is the only product that is used.

A

C10H22→2C3H6+C4H10\text{C}_{10}\text{H}_{22} \rightarrow 2\text{C}_3\text{H}_6 + \text{C}_4\text{H}_{10}C10​H22​→2C3​H6​+C4​H10​

B

C6H14→C3H6+C3H8\text{C}_6\text{H}_{14} \rightarrow \text{C}_3\text{H}_6 + \text{C}_3\text{H}_8C6​H14​→C3​H6​+C3​H8​

C

C3H7OH→C3H6+H2O\text{C}_3\text{H}_7\text{OH} \rightarrow \text{C}_3\text{H}_6 + \text{H}_2\text{O}C3​H7​OH→C3​H6​+H2​O

D

C3H7Cl→C3H6+HCl\text{C}_3\text{H}_7\text{Cl} \rightarrow \text{C}_3\text{H}_6 + \text{HCl}C3​H7​Cl→C3​H6​+HCl
