The correct statement`(s) is//are`

Options

A. `BeCl_(2)` is a covalent compound
B. `BeCl_(2)` can form dimer
C. `BeCl_(2)` is an electron-deficient molecule
D. The hybrid state of `Be` in `BeCl_(2)` is `sp^(2)`

Answer

A, B, C

Explanation

Due to high charge/radius ratio of `Be^(2+),BeCl_(2)` is covalent. Since four electrons are their in valence shell of `BeCl_(2)`. It is electron dificient and thus gets dimerise or polymerise.
