The element which can displace three other halogens from their compound is :
Among halogens, the correct order of amount of energy released in electron gain (electron gain enthalpy ) is (a) F > Cl > Br > I (b) F < Cl < Br < I (c) F < Cl > Br > I (d) F < Cl < Br < I
Which of the following arrangement for the three halogens Cl, Br and I when placed in the order of their increasing electron afinity is correct?
