Why do we use octet rule?

The octet rule states that atoms tend to form compounds in ways that give them eight valence electrons and thus the electron configuration of a noble gas. Atoms of metals tend to lose all of their valence electrons, which leaves them with an octet from the next lowest principal energy level.

Q. Why does CH3 violate the octet rule?

1 Answer. Ernest Z. B(CH3)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.

Q. How does bf3 violate the octet rule?

The Lewis electron dot diagram for NO is as follows: Boron commonly makes only three covalent bonds, resulting in only six valence electrons around the B atom. A well-known example is BF 3: The third violation to the octet rule is found in those compounds with more than eight electrons assigned to their valence shell.

Q. Does ch3 violate octet rule?

Many reactive intermediates are unstable and do not obey the octet rule. This includes species such as carbenes, borane as well as free radicals like the methyl radical (CH3) which has an unpaired electron in a non-bonding orbital on the carbon atom, and no electron of opposite spin in the same orbital.

Q. Why is a full octet more stable?

A complete octet is very stable because all orbitals will be full. Atoms with greater stability have less energy, so a reaction that increases the stability of the atoms will release energy in the form of heat or light. A stable arrangement is attended when the atom is surrounded by eight electrons.

Q. Can oxygen break the octet rule?

Octet rule: The concept that compounds containing carbon, nitrogen, oxygen, and fluorine are more stable if these atoms have eight valence electrons. When one of these atoms has less than eight valence electrons it has an open octet. Every carbon, nitrogen, oxygen, and fluorine atom in this molecule has a full octet.

Q. Why does hydrogen want a full outer shell?

The valence electrons (outer-most electrons) determine most of the bonding behavior in atoms. Atoms want a full outer shell because it completes all the gaps in the outside. With no gaps, other electrons don’t want to fit into those spaces. For example, a noble gas like Neon has a full outer shell.
