Chemistry - STRUCTURAL ISOMERISM Question with Solution | TestHub

With $\mathrm{N}{\mathrm{H}}_2$ fixed at position 1, two chlorines can occupy : 2,3- ; 2,4- ; 2,5- ; 2,6- ; 3,4- and 3,5- positions. (The ring's mirror symmetry makes 2,3 the same as 5,6, and so on.) That gives 6 distinct dichloroanilines.
