Chapter 19, Problem 77AE

Interpretation Introduction

Interpretation:

The possible structures for the given molecular formula, ${\text{C}}_{\text{5}}{\text{H}}_{\text{12}}\text{O}$ has to be identified first by changing the bonding patterns and the IUPAC names, common names has to be given.

Concept Introduction:

Ethers:

Ethers are organic compounds in which the ${\text{sp}}^{\text{3}}$ hybridized oxygen atom is directly bonded to two alkyl groups. The general formula for ethers is shown here.

Rules of common name:

• Identify and name the two alkyl groups bonded to the ${\text{sp}}^{\text{3}}$ hybridized oxygen atom in alphabetical order.
• Finally, add the word ether at the end of the alkyl group’s names.

IUPAC rules for naming ethers:

• Identify the parent carbon chain in the given compound. If two or more chains have the same carbon lengths, choose the chain with a greater number of substituents bonded to it. Name the parent carbon chain,
• The other alkyl group is named by replacing the $\text{-yl}$ ending of that alkyl group to $\text{-oxy}$. The final name looks like “alkoxy”.
• Arrange the both names, the alkoxy name first followed by the parent compound’s name as alkoxyalkane.
