Question
Chapter 16, Problem 16.68AP
Interpretation Introduction
(a)
Interpretation:
An explanation as to why the given compound is chiral is to stated.
Concept introduction:
Chiral compounds are those whose mirror images are not superimposable to each other. Enantiomers of the chiral compounds are the mirror image of each other. A compound can be chiral due to the presence of an asymmetric carbon or the chiral axis.
Interpretation Introduction
(b)
Interpretation:
An explanation as to why the given compound is chiral and it racemizes when heated is to stated.
Concept introduction:
Chiral compounds are those whose mirror images are not superimposable to each other. Enantiomers of the chiral compounds are the mirror image of each other. A compound can be chiral due to the presence of an asymmetric carbon or the chiral axis.

a
A chemist titrates 70.0 mL of a 0.7089 M hydrocyanic acid (HCN) solution with 0.4574M KOH solution at 25 °C. Calculate the pH at equivalence. The pK of
hydrocyanic acid is 9.21.
Round your answer to 2 decimal places.
Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added.
