Bond energy of F2,Cl2,Br2,I2 follows the order:

Question

Bond energy of F2,Cl2,Br2,I2 follows the order: (A)  Br2 > F2 > Cl2 > I2  (B)  F2 > Cl2 > Br2 > I2  (C)  I2 > F2 > Br2 > Cl2  (D)  F2 > I2 > Br2 > Cl2

Tardigrade Admin · Accepted Answer

Bond energy of F2, C l2, B r2 and I2 are as: F-F arrow 150.6 mol -1(k J) C l-C l arrow 242.7 mol -1(k J) B r-B r arrow 188.3 mol -1(k J) I - I arrow 150.6 mol -1(k J) Bond energy of F2 is lower because of repulsion between non bonded electrons of small sized F atom. So the order is F2 < C l2>B r2>I2

Q. Bond energy of $F_{2}, C l_{2}, B r_{2}, I_{2}$ follows the order:

$B r_{2} > F_{2} > C l_{2} > I_{2}$

$F_{2} > C l_{2} > B r_{2} > I_{2}$

$I_{2} > F_{2} > B r_{2} > C l_{2}$

$F_{2} > I_{2} > B r_{2} > C l_{2}$

Q. Bond energy of F2​,Cl2​,Br2​,I2​ follows the order:

Br2​>F2​>Cl2​>I2​

F2​>Cl2​>Br2​>I2​

I2​>F2​>Br2​>Cl2​

F2​>I2​>Br2​>Cl2​

Q. Bond energy of $F_{2}, C l_{2}, B r_{2}, I_{2}$ follows the order:

$B r_{2} > F_{2} > C l_{2} > I_{2}$

$F_{2} > C l_{2} > B r_{2} > I_{2}$

$I_{2} > F_{2} > B r_{2} > C l_{2}$

$F_{2} > I_{2} > B r_{2} > C l_{2}$
