Chapter 11.1, Problem 1P

Interpretation Introduction

Interpretation:

A number of allylic hydrogens which are present in given structure of $\text{α-terpineol}$ are to be determined. Whether the hydroxyl group present in the given structure is allylic or not is to be discussed.

Concept Introduction:

>

The allyl group contains the unit ${\text{CH=CH-CH}}_{\text{2}}$ .

>

A ${\text{sp}}^3$ carbon atom of an allyl group is the allylic carbon atom.

>

Carbon atoms which are adjacent to the double bonded carbon atoms are the allylic carbon atoms

>

The atoms or groups attached to the allylic carbon atoms are the allylic substituents.
