Chapter 13, Problem 13.29UTC

Interpretation Introduction

Interpretation:

“Identify each of the following as an alcohol, a phenol, ether, or a thiol.” should be explained

Concept introduction:

• Alcohols contain the characteristic $-\text{OH}$ functional group.
• Phenols contain the characteristic $-\text{OH}$functional group with benzene ring.
• Ethers contain the characteristic $-\text{O}-$ functional group.
• Thiols contain the characteristic $-\text{SH}$functional group

Answer to Problem 13.29UTC

Solution:

1. The given organic compound is an alcohol.
2. The given organic compound is ether.
3. The given organic compound is a thiol.
4. The given organic compound is an alcohol.

Explanation of Solution

Functional group:

The properties of organic compounds are depending on some groups of atom, which is known as functional group. Thus, the compounds, which have same functional group, have similar properties.

For example, if the compound contains at least one double bond means it is an example of alkene.

Alcohols: Alcohols contain the characteristic $-\text{OH}$ functional group.

  R-OH

  Alcohol

Phenols: Phenols contain the characteristic $-\text{OH}$ functional group with benzene ring or phenyl group.

  $\text{Ph}-\text{OH}$

  Phenol

Ethers: Ethers are organic molecules in which the functional group is doubly bonded oxygen atom ( $-\mathrm{O}-$). The general formula of ether is following:

  $\text{R}-\text{O}-\text{R}$

Thiols: thiols contain the characteristic $-\text{SH}$ functional group.

  $\text{R}-\text{SH}$

Thiol

1. Given:



This is an example of alcohol because alcohols contain the characteristic $-\text{OH}$ functional group.

2. Given:



This is an example of ether because ethers contain the characteristic $-\text{O}-$ functional group.

3. Given:

  ${\text{CH}}_{\text{3}}-\text{CH(}-\text{SH})-{\text{CH}}_{\text{3}}$

This is an example of thiol because thiols contain the characteristic $-\text{SH}$ functional group.

4. Given:



This is an example of alcohol because alcohols contain the characteristic $-\text{OH}$ functional group.

Conclusion

Therefore;

1. The given organic compound is an alcohol.
2. The given organic compound is ether.
3. The given organic compound is a thiol.
4. The given organic compound is an alcohol.
