Answer» Answer: n Hexyl bromine is a halo alkane . therefore it shows higher reactivity TOWARDS nucleophilic substitution than bromobenzene which is a haloarene On heating with aqueous KOH it FORMS KBr and n Hexyl alcohol CH3 (CH2)4 CH-Br + KOH----> CH3 (CH2)4 CH-OH +KBr The reaction mixture on acidification with dilute nitric acid followed by treatment with silver NITRATE produces a yellow precipitate of silver bromide KBr + AgNO3---->AgBr +KNO3 In contrast bromobenzene doesnot undergo hydrolysis with aq KOH
Bromobenzene + KOH --->No reaction Therefore on treating the reaction mixture with dilute nitric acid followed by silver nitrate does not PRODUCE a yellow precipitate
