Question

Which of the alkaline earth metal halides given below is essentially covalent in nature? (A) BeCl2 (B) MgCl2 (C) SrCl2 (D) CaCl2

Tardigrade Admin · Accepted Answer

Be2 + cation is very small in size and in terms of Fajan's rules brings about polarization of electronic cloud of anion (.Cl-.) i.e. BeCl2 is covalent in nature.

Q. Which of the alkaline earth metal halides given below is essentially covalent in nature?

$B e C l_{2}$

$M g C l_{2}$

$S r C l_{2}$

$C a C l_{2}$

$B e^{2 +}$ cation is very small in size and in terms of Fajan's rules brings about polarization of electronic cloud of anion $(C l^{-})$ i.e. $B e C l_{2}$ is covalent in nature.
