Vedclass · Answer

(B) The thermal stability of interhalogen compounds depends upon the difference in electronegativity between the combining atoms. $A$ larger electronegativity difference leads to a stronger bond and higher thermal stability. The electronegativity values are: $F = 4.0, Cl = 3.2, Br = 3.0, I = 2.7$. The electronegativity differences are: $ClF: |4.0 - 3.2| = 0.8$ $BrCl: |3.2 - 3.0| = 0.2$ $IBr: |3.0 - 2.7| = 0.3$ $ICl: |3.2 - 2.7| = 0.5$ Comparing these differences,the order of stability is $ClF > ICl > IBr > BrCl$.

Identify the correct decreasing order of thermal stability for the following interhalogen compounds.
