Chemistry Question on Group 17 Elements

Correct order of reactivity:

A

I2>Br2>Cl2>F2{{I}_{2}}>B{{r}_{2}}>C{{l}_{2}}>{{F}_{2}}

B

Br2>I2>Cl2>F2B{{r}_{2}}>{{I}_{2}}>C{{l}_{2}}>{{F}_{2}}

C

Cl2>Br2>I2>F2C{{l}_{2}}>B{{r}_{2}}>{{I}_{2}}>{{F}_{2}}

D

F2>Cl2>Br2>I2{{F}_{2}}>C{{l}_{2}}>B{{r}_{2}}>{{I}_{2}}

Answer

F2>Cl2>Br2>I2{{F}_{2}}>C{{l}_{2}}>B{{r}_{2}}>{{I}_{2}}

Explanation

Solution

Halogens in general are very reactive due to high electro negativity, high electron affinity and compartively low bond energies.
The reactivity of halogens decreases with increase in atomic number. The correct order of reactivity of halogens is F2>Cl2>Br2>I2F _{2} > Cl _{2} > Br _{2} > I _{2}
