MCQ
The molecule having highest bond energy is
- A$N\,-\,N$
- B$F\,-\,F$
- ✓$C\,-\,C$
- D$O\,-\,O$
✓
Answer
Correct option: C.
$C\,-\,C$
c
The molecule having highest bond energy is $C-C$. As all the given molecules are bonded together through single bond, More is The bond order of a moleule more closely its atoms will be bonded together. As a result, more strong will be the bonding between its combining atoms.
The molecule having highest bond energy is $C-C$. As all the given molecules are bonded together through single bond, More is The bond order of a moleule more closely its atoms will be bonded together. As a result, more strong will be the bonding between its combining atoms.
In the given molecules fluorine, nitrogen and oxygen atoms have lone pair electons in Them these lone pairs creates lonepair-lone pair repulsion between $F-F,N-N$ and $O-O$ molecules. Due to which it will increase its bond length and decrease the bond energy. so, The correct option is $C-C$ as there are no lone pairs present on carson atom
