विकल्प
BeCl2
MgCl2
CaCl2
SrCl2
उत्तर
Some of the Group 2 metal halides are covalent and soluble in organic solvents. Among the following metal halides, the one which is soluble in ethanol is BeCl2.
Explanation:
Due to small size, high electronegativity and high ionization enthalpy of Be, BeCl2 is covalent and hence most soluble in organic solvents such as ethanol.
