# Por que B (CH3) 3 viola a regra do octeto?

"B(CH"_3)_3 viola o regra do octeto porque o "B" atom has only six elétrons de valência in its valence shell.

O regra do octeto is a chemical rule of thumb that states that atoms of main-group elementos combine in such a way that each atom will have eight electrons in its valence shell.

A estrutura de Lewis "B(CH"_3")"_3 is

We see that the molecule has only six elétrons de valência em volta do "B" átomo.

This is a violation of the octet rule.
