Reaction : Toluene in dark conditions undergoes electrophilic aromatic substitution on the benzene ring, producing ortho and para bromotoluenes. This is correctly represented.

Reaction : The diazonium salt reacts with via the Sandmeyer reaction to produce bromobenzene. This is correctly represented.

Reaction : Toluene with light undergoes free radical substitution at the benzylic position, producing benzyl bromide ( ). This is correctly represented.
Reaction : Cyclohexene is shown producing an allylic bromination product, but cyclohexene with and light undergoes electrophilic addition across the double bond to form dibromocyclohexene or undergoes addition rather than simple allylic substitution. This representation is incorrect.
