Chapter E, Problem E.19P

Interpretation Introduction

(a)

Interpretation:

Whether trichloromethylalcohol, given in Problem E.18, is a primary, secondary, or tertiary alcohol is to be determined.

Concept introduction:

Alcohols consist of an alkyl group attached to a hydroxyl (OH) group. In primary ${\text{(1}}^{\text{o}}\text{)}$ alcohol, the OH group is attached to a primary carbon atom. In secondary ${\text{(2}}^{\text{o}}\text{)}$ alcohol, the OH group is attached to a secondary carbon atom. In tertiary ${\text{(3}}^{\text{o}}\text{)}$ alcohol, the OH group is attached to a tertiary carbon. If the carbon to which the OH group is attached is not attached to any other carbon, then the alcohol is a methyl alcohol.

Interpretation Introduction

(b)

Interpretation:

Whether isobutyl alcohol, given in Problem E.18, is primary, secondary, or tertiary alcohol is to be determined.

Concept introduction:

Alcohols consist of an alkyl group attached to hydroxyl (OH) group. In primary ${\text{(1}}^{\text{o}}\text{)}$ alcohol, the OH group is attached to a primary carbon. In secondary ${\text{(2}}^{\text{o}}\text{)}$ alcohol, the OH group is attached to a secondary carbon atom. In tertiary ${\text{(3}}^{\text{o}}\text{)}$ alcohol, the OH group is attached to a tertiary carbon atom.

Interpretation Introduction

(c)

Interpretation:

Whether pentylalcohol, given in Problem E.18, is a primary, secondary, or tertiary alcohol is to be determined.

Concept introduction:

Alcohols consist of an alkyl group attached to hydroxyl (OH) group. In primary ${\text{(1}}^{\text{o}}\text{)}$ alcohol, the OH group is attached to a primary carbon atom. In secondary ${\text{(2}}^{\text{o}}\text{)}$ alcohol, the OH group is attached to a secondary carbon atom. In tertiary ${\text{(3}}^{\text{o}}\text{)}$ alcohol, the OH group is attached to a tertiary carbon atom.

Interpretation Introduction

(d)

Interpretation:

Whether sec-butyl alcohol from Problem E.18 is a primary, secondary, or tertiary alcohol is to be determined.

Concept introduction:

Alcohols consist of an alkyl group attached to hydroxyl (OH) group. In primary ${\text{(1}}^{\text{o}}\text{)}$ alcohol, the OH group is attached to a primary carbon atom. In secondary ${\text{(2}}^{\text{o}}\text{)}$ alcohol, the OH group is attached to a secondary carbon atom. In tertiary ${\text{(3}}^{\text{o}}\text{)}$ alcohol, the OH group is attached to a tertiary carbon atom.
