प्रश्न
Arrange the halogens F2, Cl2, Br2, I2, in order of their increasing reactivity with alkanes.
पर्याय
I2 < Br2 < Cl2 < F2
Br2 < Cl2 < F2 < I2
F2 < Cl2 < Br2 < I2
Br2 < I2 < Cl2 < F2
उत्तर
I2 < Br2 < Cl2 < F2
Explanation:
The reactivity of halogens with alkanes depends on the electronegativity i.e. higher the electronegativity higher would be the reaction. As down the group reactivity decrease so thus its reactivity.
