Answer» r 1 :-❒ Explanation :-Cl₂ , Br₂ and I₂ are Homonuclear diatomic molecule in which electronegativity of the combining atoms is same. So they are more stable and less reactive, whereas I and Cl have different electronegativities and bond between them are polarized,Hence reactive therefore interhalogen COMPOUNDS are more reactive.★ Time saving technique :In this type of question of halogen only go through the polarity of molecule. As we know, diatomic molecule does not have polarity but MOLECULES with dissimilar sizes have polarity resulting in more reactivity.⇝ Answer 2 :-❒ Explanation :-H₂O₂ can act as an oxidising as well as reducing agent, because oxidation NUMBER of oxygen in H₂O₂ is -1 so it can be oxidized to Oxidation State 0 or can be reduced to Oxidation State -2 .H₂O₂ decomposes on exposure to light. So it has to be stored in plastic or wax lined glass bottles in dark for the prevention of exposure. It also has to be kept away from Dust |
