Question

The number of isomers in ${\mathrm{C}}_4{\mathrm{H}}_{10}\mathrm{O}$ are______.

Answer 1

Isomers:

• “Isomers are two or more compounds that have the same chemical formula but a different arrangement of atoms.”
• As the structures of isomers differ, thus the physical/chemical properties also differ.

Calculation of Double bond equivalent (DBE) in ${\mathrm{C}}_4{\mathrm{H}}_{10}\mathrm{O}$

$$\begin{gathered} \text{DBE=C+1-}\frac{\text{H}}{2}\text{-}\frac{X}{2}\text{+}\frac{\text{N}}{2} \\ \text{=4+1-}\frac{10}{2} \\ \text{=0} \end{gathered}$$

Structural isomers of ${\mathrm{C}}_4{\mathrm{H}}_{10}\mathrm{O}$

• The degree of unsaturation for the formula ${\mathrm{C}}_4{\mathrm{H}}_{10}\mathrm{O}$ is 0 which indicates that there is no ring or a double bond in the structure.
• The isomers of ${\mathrm{C}}_4{\mathrm{H}}_{10}\mathrm{O}$ is as follows:-

• 
• So, the number of isomers of ${\mathrm{C}}_4{\mathrm{H}}_{10}\mathrm{O}$ is seven.
