Question

Use the supplied model and data: for a common large tetrahedral anion X²⁻, thermal stability of MX is assumed to increase as M²⁺ grows from Ca to Ba; normal boiling points of C₂F₆, C₃F₈, n-C₄F₁₀ are 195K, 237K, 271K. Which statements follow?

TestHub · Accepted Answer

A applies the explicit large-anion stability assumption. The boiling values increase with molecular size, so volatility decreases and B follows. Stronger dispersion gives the ordinary explanation in C. Solubility balances lattice and hydration terms, so D is not a universal result.
