BeCl2 is obey octate rule?

Answer 1

No, BeCl2 does not obey the octet rule. The octet rule states that most atoms tend to gain, lose, or share electrons in order to have a full outer shell of eight electrons (or two electrons for hydrogen). However, beryllium only has four valence electrons and can only form two bonds. In BeCl2, beryllium forms two covalent bonds with two chlorine atoms, resulting in a linear molecule with only four valence electrons around beryllium.
