Question

2) Arrange the following in increasing order of Bond dissociation energy No-2 NONO+2, NO-1, NO+1
​

Answer 1

Answer:

No-1 , No-2 ,No+1 ,NoNo+ 2is the increasing order of bond dissociation energy

Answer 2

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
