Which phenol in each of the following pairs is more acidic? justify your choice.

a. 2,4,6-trimethylphenol or 2,4,6-trinitrophenol
b. 2,6-dichlorophenol or 3,5-dichlorophenol
c. 3-nitrophenol or 4-nitrophenol
d. phenol or 4-cyanophenol
e. 2.5-dinitrophenol or 2,6-dinitrophenol

Given the data below for the reaction, 2 a + 2 b + 4 c => d + e + 3 f, the reaction is fill in the [ ] order in a, fill in the [ ] order in b, fill in the [ ] order in c and fill in the [ ] order overall.
