Final answer:
Without specific details on the reaction conditions, it's difficult to determine the exact products of reacting NBR with toluene in the presence of light; reactions may involve substitution or addition mechanisms.
Step-by-step explanation:
The student inquired about what products would result from reacting NBR (Nitrile Butadiene Rubber) with toluene in the presence of light. Based on the related chemistry concepts, particularly involving the reaction of alkenes with halogens, we can infer a possible reaction mechanism. However, without specific details on the conditions of the reaction (e.g., type of light, presence of any catalysts, temperature) and the form of NBR used, it is challenging to provide an exact answer on the products formed.
Nevertheless, we can derive from halogenation reactions that involve alkanes and alkyl-substituted benzenes such as toluene that they can undergo reactions with halogens in the presence of ultraviolet light or at elevated temperatures. This typically results in the substitution of hydrogen atoms by halogens. Since NBR has double bonds in its structure, it could also potentially undergo additive halogenation reactions with the solvent toluene, depending on reaction conditions.
