- When the conjugate acid of aniline, C6H5NH3+, reacts with the acetate ion, the following reaction takes place: C6H5NH3+(aq)+CH3COO(aq)C6H5NH2(aq)+CH3COOH(aq) If Kafor C6H5NH3+ is 1.35105 and Kafor CH3COOH is 1.86105 , what is K for the reaction?arrow_forwardWill 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_forwardComplete the following acid-base reactions. (a) CH3CH2CH2CH2Li + CH3COOH (b) CH3CH2CH2CH2MgBr + CH3CH2OHarrow_forward
- Ethyl butyrate, CH3CH2CH2CO2CH2CH3, is an artificial fruit flavor commonly used in the food industry for such flavors as orange and pineapple. Its fragrance and taste are often associated with fresh orange juice, and thus it is most commonly used as orange flavoring.It can be produced by the reaction of butanoic acid with ethanol in the presence of an acid catalyst (H+): CH3CH2CH2CO2H(l)+CH2CH3OH(l)H+⟶CH3CH2CH2CO2CH2CH3(l)+H2O(l) a) Given 7.70 g of butanoic acid and excess ethanol, how many grams of ethyl butyrate would be synthesized, assuming a complete 100% yield? b) A chemist ran the reaction and obtained 5.25 g of ethyl butyrate. What was the percent yield? c) The chemist discovers a more efficient catalyst that can produce ethyl butyrate with a 78.0% yield. How many grams would be produced from 7.70 g of butanoic acid and excess ethanol?arrow_forwardUsing the data in Appendix C, determine which of the following bases is strong enough to deprotonate acetonitrile (CH3CN), so that equilibrium favors the products: (a) NaH; (b) Na2CO3; (c) NaOH; (d) NaNH2; (e) NaHCO3.arrow_forwardTwo methods convert an alkyl halide into a carboxylic acid having one more carbon atom. (1] R-X + "CN R-CN R,COOH COOH (Section 22.18) + X- new C-C bond [1] CO2 RCOOH (Section 20.14) [2] H3O [2] R-X + Mg R-MgX Depending on the structure of the alkyl halide, one or both of these methods may be employed. For each alkyl halide, write out a stepwise sequence that converts it to a carboxylic acid with one more carbon atom. If both methods work, draw both routes. If one method cannot be used, state why it can't. Br a. CH,CI b. c. (CH3)3CCI d. HOCH,CH,CH,CH,Brarrow_forward
- Identify the reagents necessary for the reaction:arrow_forwardThe Brønsted-Lowry definition of acids and bases is: Acids are proton donors, bases are proton acceptors Acids are nucleophiles and bases are electrophiles Acids are proton acceptors, bases are proton donors Carboxy groups are acids and amine groups are bases Carboxy groups are electrophiles and amine groups are nucelophilesarrow_forwardThe following molecule belongs to a class of compounds called enediols. Each carbon of the double bond carries an —OH group: Draw structural formulas for the α-hydroxyketone and the α-hydroxyaldehyde with which this enediol is in equilibrium. α-hydroxyketone α-hydroxyaldehydearrow_forward
