Chapter 14, Problem 23P

Classify each alcohol as 1°, 2°, or 3^o

  a. $C{H}_{3}C{H}_{2}C{H}_{2}OH$

   b. ${\left(C{H}_{3}C{H}_2\right)}_{3}COH$

Interpretation Introduction

(a)

Interpretation:

The following alcohol should be classified as $1°$ , $2°$ or $3°$.

  ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}\text{OH}$

Concept Introduction:

Compounds consist of carbon and hydrogen is known as hydrocarbons. Hydrocarbons are classified as saturated hydrocarbon and unsaturated hydrocarbon. Saturated hydrocarbons are those hydrocarbons in which carbon-carbon single bond is present as carbon is linked with four atoms. Unsaturated hydrocarbons are those hydrocarbons in which carbon-carbon multiple bonds are present that is double and triple bond.

When the hydroxyl group (-OH) is present on the carbon atom and that carbon atom is bonded to one other carbon atom is known as primary ( $\text{1}°$ ) alcohol.

When the hydroxyl group (-OH) is present on the carbon atom and that carbon atom is bonded to two other carbon atoms is known as secondary ( $2°$ ) alcohol.

When the hydroxyl group (-OH) is present on the carbon atom and that carbon atom is bonded to three other carbon atoms is known as tertiary ( $3°$ ) alcohol.

Answer to Problem 23P

Primary alcohol

Explanation of Solution

The given compound is ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}\text{OH}$.

  

According to the above structure of compound, one hydroxyl group is present on carbon atom which is linked with one other carbon atom. Thus, ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}\text{OH}$ is primary alcohol.

Interpretation Introduction

(b)

Interpretation:

The following alcohol should be classified as $1°$ , $2°$ or $3°$.

  ${{\text{(CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{)}}_{\text{3}}\text{COH}$

Concept Introduction:

Compounds consist of carbon and hydrogen is known as hydrocarbons. Hydrocarbons are classified as saturated hydrocarbon and unsaturated hydrocarbon. Saturated hydrocarbons are those hydrocarbons in which carbon-carbon single bond is present as carbon is linked with four atoms. Unsaturated hydrocarbons are those hydrocarbons in which carbon-carbon multiple bonds are present that is double and triple bond.

When the hydroxyl group (-OH) is present on the carbon atom and that carbon atom is bonded to two other carbon atoms is known as secondary ( $2°$ ) alcohol.

When the hydroxyl group (-OH) is present on the carbon atom and that carbon atom is bonded to three other carbon atoms is known as tertiary ( $3°$ ) alcohol.

Answer to Problem 23P

Tertiary alcohol

Explanation of Solution

The given compound is ${{\text{(CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{)}}_{\text{3}}\text{COH}$.

  

According to the above structure of compound, one hydroxyl group is present on carbon atom which is linked with three other carbon atoms. Thus, ${{\text{(CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{)}}_{\text{3}}\text{COH}$ is tertiary alcohol.

Interpretation Introduction
