Chemistry - STRUCTURAL ISOMERISM Question with Solution | TestHub

Molecular formula $={\mathrm{C}}_4{\mathrm{H}}_{10}\mathrm{O}$

Degree of unsaturation $=\left(\mathrm{C}+1\right)-\frac{\mathrm{H}+\mathrm{X}-\mathrm{N}}{2}=5-\frac{10}{2}=0$

Possible alcohols are:

2-butanol exhibits optical isomerism, hence, two stereoisomers need to be considered.
