Chapter 4, Problem 4.14NP
Interpretation Introduction

Interpretation:

The standard enthalpy of formation ΔH0f of CaC2(s) at 25°C needs to be calculated

Concept Introduction:

The standard enthalpy of formation ΔH0f of a compound is the enthalpy change due to the formation of 1 mole of a compound from its constituent elements in their standard state.

Hess's law of constant heat summation states that the total enthalpy change for a given reaction can be expressed as a sum of the enthalpies of the intermediate reactions i.e.

  ΔH = ΔH1+ ΔH2+ΔH3+....+ΔHn -----(1)

Here, ΔH = total enthalpy change

ΔH1, ΔH2... ΔHn are the enthalpy changes of the intermediate steps.

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.
