Answer: 2. [structure shown in figure]

Key idea: HF protonates the alkene to give a carbocation, which alkylates benzene (Friedel-Crafts alkylation).

Cyclohexene + \(H^+\rightarrow\) cyclohexyl cation, which attacks benzene to give phenylcyclohexane. Fluoride does not add, since the aryl C-C bond formation is preferred under these conditions.
