Question

Arrange F2, Cl2, Br2, I2 in increasing bond dissociation enthalapy . and give an appropriate reason to justify your answer?

Answer 1

Cl2 > Br2 > F2 > I2

Answer 2

but what is the reason behind this ?

Answer 3

the reason is the atomic orbital of F are too samall so the electrons in them try to repell each other as possible as away

mean electron density in case of F2 is higher Compared to electron density in Cl2

Answer 4

density mean nof of electron per unit volume

Answer 5

Thank You !!!

Answer 6
