Chapter 7.10, Problem 21P

Interpretation Introduction

Interpretation:

The bases which can remove a proton from terminal alkyne should be identified from the given list.

Concept Introduction:

In a reaction which strongly favours the formation of products, the base used to remove proton from the acid should be stronger than the base formed when the proton is removed.

Order of electronegativity of carbon atoms:

$\text{sp}\text{>}{\text{sp}}^{\text{2}}\text{>}{\text{sp}}^{\text{3}}$

Most electronegative is the $\text{sp}$ hybridized carbon atom.

The most acidic compound will be the hydrogen which is attached to the most electronegative carbon.
