$1 mol$ each of the following compounds is dissolved in $1 L$ of solution. Which will have the largest $Δ T_{b}$ value?

Options:

Answer:

Solution:

Bond dissociation energy increases in the order. $HI < HBr < HCl < HF$ $HF$ is most stable halogen acid and $HI$ is the least. Higher the bond dissociation energy, lower is the degree of ionisation. As we know $Δ T_{b} = i K_{b} m$ . Hence $Δ T_{b}$ value is largest in HI. All colligative properties depend on number of particles.
