Question

The decreasing order of bond energy among F2, Cl2, O2 and N2 is :
A) N2 > O2> Cl 2> F2
B) O2>F2> Cl2>N2
C) F2> CI2 > O2> N2
D)N2> O2 > F2> CI2

​

Answer 1

Explanation:

N

2

has triple bond between N atoms.

O

2

has double bond between O atoms.

F

2

and Cl

2

has single bonds between the atoms.

More the number of bonds between atoms, more will be the bond energy. Between F

2

and Cl

2

, Cl

2

has more bond energy because in F

2

, the atoms are closer and repulsions are more. So, bond energy of F

2

is less.

∴ Order of bond energies= N

2

>O

2

>Cl

2

>F
