Question

Which of the following has/have a strong covalent bond? (A) Cl-F (B)F-F (C)C-Cl. (D)C-F?

Answer 1

Well, all of them....

Explanation:

The strongest covalent bond is PROBABLY between `C-F`...the weakest bond is between `F-F`, due to unfavourable electrostatic interactions between the lone pair electrons on each fluorine centre...

As a chemist, as a physical scientist, you should consult the data...

The weakness of the `F-F` bond is quite apparent....and is to be compared with the strength of the `C-F` bond.
