B. The Lewis diagram for NO₂ is: |t8––8: =0: Recall that for predicting geometry, double and triple bonds count as only one electron pair. The electron-pair geometry around the N atom in NO₂ is There are lone pair(s) around the central atom, so the geometry of NO₂ is
Formal Charges
Formal charges have an important role in organic chemistry since this concept helps us to know whether an atom in a molecule is neutral/bears a positive or negative charge. Even if some molecules are neutral, the atoms within that molecule need not be neutral atoms.
Polarity Of Water
In simple chemical terms, polarity refers to the separation of charges in a chemical species leading into formation of two polar ends which are positively charged end and negatively charged end. Polarity in any molecule occurs due to the differences in the electronegativities of the bonded atoms. Water, as we all know has two hydrogen atoms bonded to an oxygen atom. As oxygen is more electronegative than hydrogen thus, there exists polarity in the bonds which is why water is known as a polar solvent.
Valence Bond Theory Vbt
Valence bond theory (VBT) in simple terms explains how individual atomic orbitals with an unpaired electron each, come close to each other and overlap to form a molecular orbital giving a covalent bond. It gives a quantum mechanical approach to the formation of covalent bonds with the help of wavefunctions using attractive and repulsive energies when two atoms are brought from infinity to their internuclear distance.
![**B. The Lewis diagram for NO₂ is:**
\[
\begin{array}{c}
{: \cdot \over \cdot :} \\
O = N - O \cdot
\end{array}
\]
**Recall that for predicting geometry, double and triple bonds count as only one electron pair.**
The **electron-pair geometry** around the N atom in NO₂ is
There are ____ lone pair(s) around the central atom, so the geometry of NO₂ is ____.
**Explanation:**
- The diagram shows the Lewis structure of NO₂, with a nitrogen atom (N) centrally bonded to two oxygen atoms (O).
- The right oxygen atom has a single dot representing a lone electron, while the left oxygen is represented with a double bond.
- The statement emphasizes that multiple bonds (double, triple) should be counted as a single electron pair when determining the molecular geometry.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2860bcf7-9e8d-460b-a0cf-53a1e326bc6d%2Fc0a88ec2-65dd-4e19-a7c9-aadb400199ab%2Fmvnmzof_processed.jpeg&w=3840&q=75)
