A generic Lewis structure is given where Y represents the central atom and the outer atoms are represented by X. The outer atoms are not necessarily all the same element. Which compound is represented by the generic Lewis structure? CHF; CH4 O CH,Cl, CF4 SiH,F
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.
### Question:
**Which compound is represented by the generic Lewis structure?**
1. \( \text{CHF}_3 \)
2. \( \text{CH}_4 \)
3. \( \text{CH}_2 \text{Cl}_2 \)
4. \( \text{CF}_4 \)
5. \( \text{SiH}_3 \text{F} \)
### Explanation:
Given the generic Lewis structure, you need to identify which of the compounds listed matches the described bonding arrangement.
For the Lewis structure depicted:
- A central atom (Y) is bonded to four outer atoms (X).
- The outer atoms each have three lone pairs of electrons.
To find the correct compound, consider the possible compounds listed:
- **CHF\(_3\)**: Contains one Carbon atom bonded to one Hydrogen atom and three Fluorine atoms.
- **CH\(_4\)**: Contains one Carbon atom bonded to four Hydrogen atoms.
- **CH\(_2\)Cl\(_2\)**: Contains one Carbon atom bonded to two Hydrogen atoms and two Chlorine atoms.
- **CF\(_4\)**: Contains one Carbon atom bonded to four Fluorine atoms.
- **SiH\(_3\)F**: Contains one Silicon atom bonded to three Hydrogen atoms and one Fluorine atom.
Based on the structure where each outer atom has three lone pairs (indicating likely Fluorine atoms), it matches \( \text{CF}_4 \), where a central Carbon atom is bonded to four Fluorine atoms.
### Answer:
**\( \text{CF}_4 \)**
This exemplifies a central atom (Carbon) bonded to four outer atoms (Fluorine),](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7d591113-c73d-4bf8-a1b7-9966513ce440%2Fddda4281-0170-49a3-a987-e20804c90de1%2Fevx6x9fo_processed.png&w=3840&q=75)
