The bond enthaply of halogens decreases down the group so why is the reactivity of halogens with hydrogens decreases down the group? Non-metal atoms gain electrons when they react with metals. They are unusual in that they are coloured and diatomic. UP CPMT 2015: The correct order of reactivity of halogen is (A) F > Cl > Br > I (B) F < C l < B r < I (C) F < Cl > Br > I (D) F > Cl < Br < I. The order of reactivity can be determined by adding acid to different metals and observing the rate of reaction. Halogens are highly electronegative, with high electron affinities. Try the given examples, or type in your own problem and check your answer with the step-by-step explanations. Viewed 2k times 2. Ask Question Asked 2 years, 11 months ago.

A route for avoiding defects during additive manufacturing ; Ultraviolet light exposure enhances the protective ability of synthetic melanin; Scientists discover potential method to starve the bacteria … Reactivity of Halogen ; Melting Point and Boiling Point; Density & Electronegativity & Solubility ; Color of Halogens; Density & Electronegativity & Solubility . Ask your question. The reactivity of Group 7 elements decreases down the group. 1) I can only answer this question .the most reactive halogen is fluor and the reactivity decreases in that order. Fluorine is one of the most reactive elements. The high reactivity of alkyl halides can be explained in terms of the nature of C — X bond which is highly polarized covalent bond due to large difference in the electronegativities of carbon and halogen atoms. 2.
