MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

The thermal stability of interhalogen compounds of the type XY with respect to disproportionation follows the order: ClF > ICl > IBr > BrCl > BrF Bromine monofluoride (BrF) is highly unstable and rapidly undergoes disproportionation at room temperature to form bromine trifluoride and bromine: 3BrF BrF_3 + Br_2 Because of its high tendency to decompose, BrF has the lowest thermal stability among the given options.
