Chemistry - STRUCTURAL ISOMERISM Question with Solution | TestHub

As about the double bond, two geometrical isomers are possible and the compound is having one chiral carbon atom so there are two optical isomers . It means it has four stereo isomers.
$\mathrm{C}{\mathrm{H}}_3-\mathrm{C}\mathrm{H}=\mathrm{C}\mathrm{H}-{}^{\mathrm{*}}\mathrm{C}\mathrm{H}\left(\mathrm{O}\mathrm{H}\right)-\mathrm{C}{\mathrm{H}}_3$
Total G.I =$2^{\mathrm{n}}=2^1=2$
Total O.I =$2^{\mathrm{n}}=2^1=2$
Here n = number of double bonds or number of chiral carbon atoms.
