Q. A compound X undergoes tetramerisation in a given organic solvent. The vant Hoff factor is

$V_{final} =4 V_{intial}$

$V_{f ina l} = 6 V_{int ia l}$

$C a F_{2} (K_{s p} = 1.7 \times 10^{- 10})$

$10^{- 4} M C a^{2 +} + 10^{- 4} M F^{-}$

$1 - α 4 A \frac{α}{4} (A)_{4}$ $i = \frac{1 - α + \frac{α}{4}}{1} = 1 - \frac{3}{4} α$ $α$ = degree of association $= 1 = 100$ $∴$ $i = 1 - \frac{3}{4} = 0.25$
