a. When removing an acidic proton, which is a stronger reagent, K or Na?

b. Do electron donating groups increase or decrease acidity? What would be a good oxide reagent to treat such groups with?

c. Do electron withdrawing groups increase or decrease acidity? What would be a good oxide reagent to treat such groups with?

d. Does resonance (like in phenols) increase or decrease acidity? What would be a good oxide reagent to treat such groups with?

Answer #1

a) K atom is larger in size than Na atom

and the size of H atom is small....so in KH ; the removal of H is easier as here there is dissimilarity in size... and the proton is more acidic in case of KH...

so K is stronger reagent than Na

    Please help me to find the answer Challenge Problem 08.94 9-Borabicyclo[3.3.1]nonane (9-BBN) is a reagent commonly used in the hydroboration of alkynes, but it can also be employed in reactions with alkenes. The following table provides the relative rates of hydroboration (using 9-BBN) for a variety of alkenes (J. Am. Chem. Soc. 1989, 111, 1414-1418) : Relative Reactivity Alkenes CH—CHОBU, 1 CH2 CHBu, 2 CH2-CHCH2OMe, 3 CH CHOAC, 4 CH2 CHCH2OAC, 5 сH—CHCH,CN, 6 CH2 CHCH2C, 7 cis-2-Butene, 8 tans-CH,CH,CHСHC,...

    This is a Synthesis of Azo Dyes lab EXPERIMENT 8: SUPPLEMENTARY LAB QUESTIONS 1. Would you expect benzoic acid or anisole to be a more effective coupling reagent? Why? Anisole would be more effective coupling agent reagents than benzoic acid because anisole has o-cH₃ an electron donating group whereas benzoic acid have a 2-oh group attached to the benzene ring that acts as electron withdrawing group. 2. Most diazo coupling reactions do not work well in acidic solutions. Explain. 3....
