Question

Highest bond energy for a single bond among the following is of:

• A. $F-F$
• B. $O-O$
• C. $C-C$
• D. $N-N$

Answer 1

The correct option is C $C-C$

$C-C$ bond energy is maximum as -
(a) Carbon shows maximum catenation.
(b) During catenation, all the $4$ valence electrons of carbon are used in bond formation, thus has no lone pair.
Hence, $C-C$ bond shows maximum bond energy. All other elements have lone pair of electrons in their valence shell after making the bonds.
(under normal conditions).
