Question

Toluene (C7H8) is methyl derivative of benzene. Which alkane will be suggested for the preparation of toluene by the method of aromatization? Kindly answer sir/mam.

Answer 1

2-methyhexane is used for preparation of toluene

Answer 2

Answer: The alkane used is n-heptane.

Explanation:

IUPAC naming for toluene is methyl benzene. It can be prepared from the straight chain alkanes, when they are heated in the presence of $Al_2O_3$ and $Cr_2O_3$ at around 500-600°C. This results in the cyclization followed by dehydrogenation. the reaction results in the aromatization of alkanes.

The alkane used for this is n-heptane.

The reaction for this is given below in the image.
