Which molecule does not obey the Octate rule of valence electrons . BeCl2

FeCl2

CuCl2

ZnCl2

Explanation:

BeCl2

The octet rule is a chemical rule of thumb that reflects the theory that main-group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.

Which molecule does not obey the Octate rule of valence electrons .

BeCl2

FeCl2

CuCl2

ZnCl2

→BeCl2

Explaination:

BeCl2 violates the octet rule because the boron should be in a suitable valence state such that it binds to 3 chlorines. However, in this molecule boron is associated with six electrons.
