Chapter E, Problem E.1P

Interpretation Introduction

(a)

Interpretation:

The IUPAC name for the given compound is to be written.

Concept introduction:

In naming organic compounds, first identify the longest carbon chain or a ring containing the functional group. Name the parent chain or a ring by replacing ‘e’ from the name of the parent alkyl chain by ‘ol’ for alcohol functional group. Number the carbon chain in a way that the functional group gets the lowest number.

Answer to Problem E.1P

The IUPAC name for the given compound is $\text{Butan-2-ol}$.

Explanation of Solution

The given compound is

In this compound, the functional group is alcohol. The parent is a four carbon atoms chain, therefore, the parent name is butanol. The carbon atoms in the parent chain are numbered starting from the carbon where the functional group gets the lowest number.

In the above compound, the functional group $\text{OH}$ is present at C2, thus the IUPAC name for the given compound is $\text{Butan-2-ol}$.

Conclusion

IUPAC name for the given compound is written.

Answer to Problem E.1P

The IUPAC name for the given compound is $\text{Butan-1-ol}$.

Explanation of Solution

The given compound is

In this compound, the functional group is alcohol. The parent is of four carbon atoms chain, therefore, the parent name is butanol. The carbon atoms in the parent chain are numbered starting from the carbon where the functional group gets the lowest number.

In the above compound, the functional group $\text{OH}$ is present at C1, thus the IUPAC name for the given compound is $\text{Butan-1-ol}$.

Conclusion

IUPAC name for the given compound is written.

Answer to Problem E.1P

The IUPAC name for the given compound is $\text{Cyclopropanol}$.

Explanation of Solution

The given compound is

In this compound, the functional group is alcohol. The parent is a ring of three carbon atoms, so, the parent name is cyclopropanol. The carbon atoms in the parent ring are numbered starting from the carbon where the functional group gets the lowest number.

In the above compound, the functional group $\text{OH}$ is present at C1, thus the IUPAC name for the given compound is Cyclopropanol.

Conclusion

IUPAC name for the given compound is written.
