Interpretation: The experimental evidence that disapproves the given mechanism is to be explained.
Concept introduction: The chemical reaction which proceeds through the formation of radicals is known as chain reaction. It involves three steps, initiation, propagation and termination. The initiation step occurs in the presence of light. The quantum yield of chain reactions is very high.

- Define " reaction mechanism." Define "nucleophile." What electronic features characterize a nucleophile? Define "electrophile." What electronic features characterize an electrophile?arrow_forwardBelow you will find twelve (12) reaction products (labeled product 1, product 2, etc.), but you will only find five (5) reaction schemes. Your job is to match the reaction scheme with the correct product. Simply fill in the blank with the product number (i.e. 1, 2, 3, etc.). Then, answer any additional questions regarding the reaction scheme(s).

The reaction of methoxide anion with bromoethane to yield the ether ethyl methyl ether and the bromide anon (Br-) is an excellent example of a general reaction type called Sy2 (substitution nucleophilic bimolecular): CH,0+ CH,СH-Br a CH3-0-CH,СH; + Br- a. Change in enthalpy is -103 kJ/mol; the change in entropy is + 0.025 kJ/mol-K. Calculate DG at 300K. b. Is the reaction endergonic or exergonic? c. Is the reaction endothermic or exothermic? d.
