MHT CET 2024 Chemistry question

Identify a compound having highest thermal stability

(A)ICl
(B)BrCl
(C)BrF
(D)ClFCorrect

Answer: (D)

Solution

Thermal stability of an interhalogen compound depends on its X-X' bond strength. The bond dissociation energies are approximately: Cl-F 252 kJ/mol, Br-F 249 kJ/mol, Br-Cl 218 kJ/mol, I-Cl 208 kJ/mol. Fluorine
