Chapter 7.10, Problem 26P

(a)

Interpretation Introduction

Interpretation:

The stable carbocation among the given cations should be identified.

Concept Introduction:

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.
