Phenylmethane is a simple aromatic compound where a methyl group (CH\(_3\)) is attached to a benzene ring. The IUPAC name for this compound is toluene, as it consists of a methyl group (CH\(_3\)) attached to a benzene ring.
- Option (A) is incorrect because benzyl alcohol has a hydroxymethyl group (-CH\(_2\)OH) attached to the benzene ring, not a methyl group.
- Option (C) is incorrect as "benzene methane" is not the IUPAC name for this compound.
- Option (D) is incorrect because methylbenzene is a less specific name for toluene. Toluene is the correct IUPAC name.
Therefore, the correct answer is option (B).
