Answer 1

⇝ Answer 1 :-

$\pink{\large\underline{\underline{\frak{\pmb{\text Correct \: Option = (4) }}}}}$

❒ 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 :-

$\pink{\large\underline{\underline{\frak{\pmb{\text Correct \: Option = (1) \: }}}}}$

❒ 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

Answer 2

$\huge\underline{\colorbox{red}{★Answer \: 1}}$

Cl2, Br2 and I2 are homonuclear and are not polarised. So these are less reactive. On the other hand, ICl is polarised due to the electronegativity difference between I and Cl and so it is the most reactive among the given options.

Hence,4 is the correct option.

$\huge\underline{\colorbox{red}{★Answer \: 2}}$

Option 1 is the correct option.

H202 can undergo reduction as well as oxidation because oxidation number of oxygen in H202 is -1. So, it can act both as reducing agent and oxidising agent.

In adidition,

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. And also has to be kept away from dust.
