JEE Main 2026 — Haloalkanes and Haloarenes Question with Solution

Reaction (1): Toluene + $B{r}_2$/Fe in dark conditions undergoes electrophilic aromatic substitution on the benzene ring, producing ortho and para bromotoluenes. This is correctly represented.
Reaction (2): The diazonium salt reacts with $C{u}_{2}B{r}_2$/HBr via the Sandmeyer reaction to produce bromobenzene. This is correctly represented.
Reaction (3): Toluene + $B{r}_2$ with light ($h\nu$) undergoes free radical substitution at the benzylic position, producing benzyl bromide (CH₂Br). This is correctly represented.
Reaction (4): Cyclohexene is shown producing an allylic bromination product, but cyclohexene with $B{r}_2$ and light undergoes electrophilic addition across the C=C double bond to form dibromocyclohexene or undergoes addition rather than simple allylic substitution. This representation is incorrect.
