Chapter 11, Problem 11.11P
Interpretation Introduction

Interpretation:

Value of pH of a solution of dibasic compound piperazine (B) has to be calculated. Also concentration of B, BH+ and BH22+ has to be determined.

Concept Introduction:

Ionic product of water is denoted by Kw and is expressed as follows:

  Kw=KaKb

Here,

Ka is acid equilibrium constant.

Kb is base equilibrium constant.

pH of solution is defined as the negative logarithm of concentration of H+. It is expressed as follows:

  pH=log[H+]

Please answer the question and provide a detailed drawing of the structure. If there will not be a new C – C bond, then the box under the drawing area will be checked.  Will the following reaction make a molecule with a new C – C bond as its major product:  Draw the major organic product or products, if the reaction will work. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry.
Please do not use AI.  AI cannot "see" the molecules properly, and it therefore gives the wrong answer while giving incorrect descriptions of the visual images we're looking at.  All of these compounds would be produced (I think).  In my book, I don't see any rules about yield in this case, like explaining that one product would be present in less yield for this reason or that reason.  Please explain why some of these produce less yield than others.
