Question
When acetylene is passed through red hot metal tubes, some molecules trimerize to form benzene. The molecular mass of the gaseous mixture, when acetylene is passed through the tube is 60. The degree of trimerization of acetylene is
Options
A.0.85
B.0.60
C.0.15
D.0.283
Solution
$\alpha = \frac{M_{o} - M}{(n - 1).M} = \frac{26 - 60}{\left( \frac{1}{3} - 1 \right) \times 60} = 0.85$
