- Will acetylene react with sodium hydride according to the following equation to form a salt and hydrogen, H2? Using pKa values given in Table 4.1, calculate Keq for this equilibrium.arrow_forwardWhy is K2HPO4 a weaker base than KOH?arrow_forwardWhich of the following two acids has the stronger conjugate base? Nitrous acid, Ka = 7.1 x 10–4 Phenol, Ka = 1.0 x 10–10 The strength of the conjugate base cannot be obtained from the information given. Nitrous acid, because it has a larger Ka value. Nitrous acid, because it has a smaller Ka value. Phenol, because it has a larger Ka value. Phenol, because it has a smaller Ka value.arrow_forward
- Show how methanol (CH3OH) can serve as both an acid and a base. Write an equation for the reaction of methanol with sulfuric acid.arrow_forwardDraw an energy diagram for the Brønsted–Lowry acid–base reaction of CH3CO2H with −OC(CH3)3 to form CH3CO2− and (CH3)3COH. Label the axes, starting materials, products, ΔH°, and Ea. Draw the structure of the transition state.arrow_forwardDescribe the acidity/basicity of each species and estimate the position of each equilibrium. CH3CH₂O + CH3C=CH CH3CH₂OH + H3CC=C b d a On the left, a is the and b is th✓ On the right, c is the and d is tl The species favored at equilibrium are those stronger acid stronger base weaker acid weaker base C Carrow_forward
- Consider the two following nitrophenol structures: OH OH `NO2 NO2 p-nitrophenol m-nitrophenol Predict which will be the stronger acid. (Hint: Consider possible resonance structures analogous to those given in the text for phenol.)arrow_forwardThe pKa of ascorbic acid (vitamin C, page 55) is 4.17, showing that it is slightly more acidic than acetic acid (CH3COOH, pKa 4.74). Compare the most stable conjugate base of ascorbic acid with the conjugate base of acetic acid, and suggest why these two compounds have similar acidities, even though ascorbic acid lacks the carboxylic acid (COOH) group.arrow_forwardWhen the reaction below reaches equilibrium, does the equilibrium lie on the left or the right side? Briefly explain.ClO– + CH3CO2H ⇌ HClO + CH3CO2–arrow_forward
- The acid dissociation constant K of trimethylacetic acid (HC(CH³)₂CO₂) is 9.33 × 10¯6. a Calculate the pH of a 3.6M solution of trimethylacetic acid. Round your answer to 1 decimal place. pH = - 0 X Śarrow_forwardGlycolic acid, HOCH2CO2H, is the simplest member of a group of compounds called αhydroxy acids, ingredients in skin care products that have an OH group on the carbon adjacent to a CO2H group. Would you expect HOCH2CO2H to be a stronger or weaker acid than acetic acid, CH3CO2H?arrow_forwardNaHCO3 can deprotonate benzoic acid but cannot deprotonate phenol. On the other hand, NaOH can deprotonate both benzoic acid and phenol. Given this information, rank the molecules numbered I to V in order of decreasing acidity.
