Why does toluene have a high boiling point?
The lower symmetry of toluene molecules prevents them from packing as efficiently as benzene molecules. … In contrast, the boiling point of toluene is higher than that of benzene, indicating that
the intermolecular attractive forces are larger in liquid toluene than in liquid benzene
.
Is toluene a drug?
Toluene, a
common organic solvent
that for some individuals is a substance of abuse, has been recognized as a neurotoxin that damages cerebral white matter. As the primary solvent in spray paints, thinners, lacquers, and glues, toluene is inhaled for its capacity to cause euphoria.

Is toluene a carcinogen?
Studies in workers and animals exposed to toluene generally indicate that
toluene is not carcinogenic
(cancer-causing). The International Agency for Research on Cancer determined that toluene is not classifiable as to its carcinogenicity in humans (Group 3).
Is toluene ortho or para directing?
For example, the nitration of methyl benzene (toluene) will produce ortho and para nitrotoluene as the main product because the methyl group is an
ortho‐para director
. However, methylating nitrobenzene leads to the formation of meta nitrotoluene because the nitro group is meta directed.
