2 bromobenzene has bromine in ortho position and 2chloro benzene has chlorine in orthoposition therefore there will be hydrogen bond between H and Cl in 2chloro benzene  and hydrogen bond between H and Br in 2 bromobenzene . Cl has more electronegativity than Br.  2chloro  benzene has stronger hydrogen bond due to more electronegativity therefore it requires more temperature to break Hion than in 2 bromobenzene.since proton donor is acid therfore 2 bromo benzoic acid is more acidic than 2 chloro benzoic acid
