Vedclass · Answer

(B) $1$. Thermal stability of interhalogen compounds depends on the difference in electronegativity between the two halogen atoms.$2$. $A$ larger difference in electronegativity leads to a stronger polar bond, resulting in higher thermal stability.$3$. The electronegativity values are: $F = 4.0$, $Cl = 3.0$, $Br = 2.8$, $I = 2.5$.$4$. Calculating the electronegativity difference $(\Delta EN)$:- For $IBr$: $|2.5 - 2.8| = 0.3$- For $BrCl$: $|2.8 - 3.0| = 0.2$- For $BrF$: $|2.8 - 4.0| = 1.2$- For $ClF$: $|3.0 - 4.0| = 1.0$$5$. Since $BrCl$ has the smallest electronegativity difference $(0.2)$, it has the weakest bond and therefore the lowest thermal stability.

Which of the following interhalogen compounds has the lowest thermal stability?
