Question 38

Propan-1-ol, $C3H7OH\text{C}_3\text{H}_7\text{OH}$ , can be dehydrated to make propene, $C3H6\text{C}_3\text{H}_6$ , according to the equation:

\text{C}_3\text{H}_7\text{OH} \rightarrow \text{C}_3\text{H}_6 + \text{H}_2\text{O}

Calculate the atom economy for the production of propene from propan-1-ol.

Relative formula masses ( $M_r$ ):

$C3H7OH=60.0\text{C}_3\text{H}_7\text{OH} = 60.0$
$C3H6=42.0\text{C}_3\text{H}_6 = 42.0$
