Chapter 26, Problem 23E

Interpretation Introduction

Interpretation:

The isomers of C₄H₁₀O that are ethers need to be depicted.

Concept introduction:

1. Isomers are two or more compounds which have the same formula but different structures and properties.
2. Constitutional isomers are structural isomers which have the same molecular formula but different connectivity of the constituent atoms.
3. Stereoisomers are spatial isomers which have the same formula and connectivity but differ in the orientation of the constituent atoms in space.
4. Ethers are organic functional groups where an oxygen atom is connected to two alkyl or aryl groups i.e. R-O-R’.
5. The degree of unsaturation i.e. the presence of multiple bonds or rings in a compound based on its molecular formula can be determined using the following equation:

$\begin{array}{l}\text{Degree of Unsaturation = }\frac{1}{2}(\text{2C+N-X-H+2) ------(1)}\\ \text{Where: C, N, X and H are the number of carbon, nitrogen, halogen and hydrogen atoms}\text{.}\end{array}$
