In the procedure for the synthesis of hexaphenylbenzene, a diels-alder reaction occurs and we needed to ensure all the starting materials were dry. after the reaction, we also washed with hexanes and toluene.
what is the purpose of this two things? also worth mentioning silicon oil was used as a solvent

answer

the ions in solute supperate from eachouthere

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

the answer is 1 i believe
