Is this how you tell when to form double bonds when drawing lewis structures, such as with CO2?
Sonic7145 said:2nd one since the others don't fulfill the octet rule?
Sonic7145 said:Thanks, but still wondering about an answer to my question. If they say it has a -2 charge, do you do that for the C or for the O? C right?
And for FC 0, you just do the octet rule correct?
Sonic7145 said:And a somewhat related question, how do we know that C,N,O,F all have four orbitals?
A Lewis structure is a diagram that shows the bonding between atoms in a molecule and the placement of lone pairs of electrons. It is named after Gilbert N. Lewis, who first described them in 1916.
The number of bonds that an atom can form is determined by its valence electrons. If an atom has less than an octet (8 electrons) in its outermost energy level, it can form double or triple bonds to achieve a more stable electron configuration.
There are several rules to follow when drawing Lewis structures, including the octet rule, which states that atoms will share, gain, or lose electrons in order to achieve a full outer shell of 8 electrons. Another rule is the duet rule, which applies to hydrogen and states that it only needs 2 electrons to achieve a full outer shell.
No, double bonds can only form between atoms that are able to share electrons in a covalent bond. This means that the atoms must have similar electronegativities and be able to overlap their orbitals to share electrons.
Double bonds are important in determining the shape, polarity, and reactivity of molecules. They also play a role in the strength of intermolecular forces, such as dipole-dipole interactions and hydrogen bonding.
