2. For a solution equimolar in HCN and NaCN, which statement is false? a. This is an example of the common ion effect. b. The [H+] is larger than it would be if only the HCN was in solution. c. The [H+] is equal to the Ka. d. Addition of more NaCN will shift the acid dissociation equilibrium of HCN to the left. e. Addition of NaOH will increase [CN–] and decrease [HCN]. please explain option B and C

OH H+ CH3 H3C OH Esters can be synthesized by an acid-catalyzed nucleophilic acyl substitution between an alcohol and a carboxylic acid; this process is called the Fischer esterification reaction. Because the alcohol oxygen is a poor nucleophile, the carbonyl carbon is made a better electrophile by protonation of the carbonyl oxygen. The steps of the synthesis are all reversible. The reaction is generally driven to completion by using an excess of the liquid alcohol as a solvent, or by...

THe enthalpy of neutralization of HCN (aq) with NaOH (aq) is -12.0 kJ/mol. Using your value for the enthalpy of neutralization of H+(aq) with OH-(aq) and the technique used in question 2, determine the enthalpy of ionization of HCN. Compare the relative amounts of ionization of HCL and HC2H3O2. Which is the stronger acid? Question 2. The neutralization of HC2H3O2 (aq) by NaOH(aq) (part C) can be considered to be the sum of the neutralization of H+(aq) by OH-(aq) (part...

To answer the questions below use the following information: Cyanohydrins are important intermediates in the synthesis of c-hydroxycarboxylic acids from ketones and aldehydes. The nitrile functional group can be hydrolyzed by aqueous acid to yield a carboxylic acid. Nitriles can also be hydrolyzed to carboxylic acids using aqueous base. Unfortunately, when a cyanohydrin is treated with aqueous base the original carbonyl compound is isolated OH CHCOOH HO CN OBU H HCEN H NAOH H20...
