7.
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. Use curved arrows to show the complete
mechanism.
