Which of following is least soluble in ethanol?
BeF2
BeCl2
BeBr2
BeI2
As we learn
Solubility of BeX2 (and BeF2) (Exception) -
is covalent in nature , so soluble in organic solvents, except
which is soluble in water
- wherein
Due to smaller size of
BeF2 is ionic; hence it is least soluble in organic solvent.
