Answer

The structure fails to obey the octet rule because Beryllium only has 4 valence electrons. Silicon fails to obey the octet rule because it has an expanded octet of 12 valence electrons. Chlorine does not obey the octet rule because it only has 7 valence electrons. Boron fails to obey the octet rule because it has an incomplete octet of six valence electrons. Xenon fails to obey the octet rule because it has an expanded octet of ten valence electrons.
