Chemistry - STRUCTURAL ISOMERISM Question with Solution | TestHub

Key Idea Compounds which have at least one double bond $(\mathrm{C}=\mathrm{C})$ and the groups attached with double bonded carbon atoms are different, exhibit geometrical isomerism.
${\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{CH}}_2{\mathrm{CH}}_2\mathrm{OH}\Rightarrow$ no geometrical isomers butanol ${\mathrm{CH}}_3\mathrm{C}\equiv {\mathrm{CCH}}_3\Rightarrow$ no geometrical isomers $${\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{C}(\mathrm{OH})={\mathrm{CH}}_2$$ $\Rightarrow$ no geometrical isomers.
