Question

Find actual division of 3/7 without decimal expansion

Answer 1

Answer:

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
