Question

please give me two solutions and the reason ;. why the Br-Br bond is weaker than the C-Br bond ?

Answer 1

Radius of Br is bigger than C as result bond Br-Br is longer than C-Br. This is the reason why Br-Br is weaker than C-Br.

Or Br-Br is nonpolar bond. C-Br – polar as result exist additional electrostatic interaction between C and Br. As reault C-Br is stronger bond than Br-Br.
