Which of the following will have the lowest bond energy?
|
|
N-N
|
|
|
N-O
|
|
|
N-F
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -The bond energies of N≡N, H−H and N−H bonds are 945, 436 and 391 KJ/mole respectively.
Detailed explanation-2: -Hence, larger size element will have less repulsion of the lone pair between atoms of diatomic of diatomic molecules & bond energy will be greater. Thus, F2 will have least bond energy.
Detailed explanation-3: -N-N and O-O single bonds are pretty weak, so usually we try not to put them in Lewis structures, unless nothing else makes sense. The structure will be better if we can make a multiple bond or put some other atom in between.
Detailed explanation-4: -The bond in lithium molecule is weakest.
