Compare the IR spectra of your purified product and the indene starting material. They will be rather similar, with one big difference. Describe the nature (frequency, broadness, strength) of the new peak in the product spectrum and explain what functional group this new peak denotes.

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 c i took the test
