"B(CH"_3)_3 violates the octet rule because the "B" atom has only six valence electrons in its valence shell.

The octet rule is a chemical rule of thumb that states that atoms of main-group elements combine in such a way that each atom will have eight electrons in its valence shell.

The Lewis structure of "B(CH"_3")"_3 is

We see that the molecule has only six valence electrons around the "B" atom.

This is a violation of the octet rule.
