Carbon Tetrafluoride (CF4) Lewis Structure

The Lewis framework is a diagrammatic depiction of identify the position of valence electrons in ~ an atom. Moreover, the diagram helps v determining just how these valence electrons get involved in the bond development either through getting embraced or donated to one more atom.

It is necessary to understand in which covering the electrons room orbiting together with their power levels to more study the hybridization of a molecule. It is the Lewis framework only whereby we deserve to study the molecular orbital diagram that a molecule.

As us know, to study the Lewis framework of any kind of compound, we first need to analyze the framework of participating atoms. The atomic number of the carbon is 6 which renders its digital configuration 1s2 2s2 2p2.

As we know, the p shell needs to accommodate 6 valence electrons in that is outermost shell, over there is a dearth the 4 valence electrons. This makes the valence electrons in carbon 4. Whereas, in the case of fluorine, its atomic number is 9 for which the electronic configuration is 1s2 2s2 2p5.

Besides this, we recognize chemistry is full of exceptions, therefore is the case with the fluorine atom. The valence electron are likewise those which are current in the highest possible principal power levels which space 2s and 2p for fluorine. This provides the valence electrons in the fluorine atom 7.

Here that is vital to know first what the valence electrons are? The electrons obtainable in the outermost shell of an atom are called valence electrons. Just these electrons take part in the bond development as castle are current farthest from the nucleus.

Due to this, the force of attraction through the cell core does no reach properly to these electrons. Even the slightest excitation by any surrounding atom, these electrons readily bonds with them to form a new compound having brand-new properties altogether.

Now, let’s learn to draw the Lewis structure of carbon tetrafluoride (CF4) through steps:

Step 1: Find the total number of valence electrons every carbon tetrafluoride (CF4) molecule has: it is 32 as 4 room coming native the carbon atom and 7 room coming from each fluorine atom.

Step 2: Find just how many more valence electrons are necessary by every carbon tetrafluoride (CF4) molecule: that is 8 together 4 an ext are necessary by the carbon atom and one every by a fluorine atom.

Step 3: Look for the main atom in every carbon tetrafluoride (CF4) molecule: Usually, the main atom is the one the is current as the single entity in ~ the molecule. They have tendency to do the maximum variety of bonds with various other participating atoms.

Step 4: Look because that the type of bonds formed in each carbon tetrafluoride (CF4) molecule (single, double, or triple bond).

Only a single covalent shared bond is formed in between the participating atoms.

Now merge all the above-mentioned points and also draw the Lewis structure of the carbon tetrafluoride (CF4) molecule:


Carbon Tetrafluoride (CF4) molecular Geometry

CF4 is a Penta-atomic molecule having a bond edge of 109.5° which offers rise come a tetrahedral shape.

It have the right to be learned in information with the help of the Valence covering Electron Pair Repulsion (VSEPR) concept that in the existence of lone pair of electrons, the molecule often tends to follow the ideal conditions.

Below is the enclosed VSEPR chart.


Carbon tetrafluoride (CF4) is the AX4E0 form structure wherein ‘A’ to represent carbon, ‘X4’ represents four fluorine atoms and also ‘E0’ to represent zero lone pair the electrons.

Molecular geometry is the 3-dimensional chart showing exactly how electrons have actually bonded to determine a concrete worth for bond angle, shortcut type, and also molecular structure, and also other geometrical parameters.


You can read about the molecule geometry of any type of molecule just after illustration its Lewis framework as it identify the number and also positioning of the valence electrons within the molecule.

Carbon Tetrafluoride (CF4) Hybridization

The hybridization of the main atom in one carbon tetrafluoride molecule (CF4) is sp3. It is due to the fact that one carbon atom and 4 fluorine atoms room bonding to complete all the including octet.

Here, one 2s and also three 2p orbitals that the same atom mix and overlap to produce four new atomic orbitals of equal energy.

Moreover, all the fluorine atoms use these newly created four hybrid orbitals that the carbon atom come bond and type the carbon-hydrogen sigma bonds. This ultimately leads to the formation of the carbon fluoride molecule.


The solitary shared covalent binding consist of only sigma bonds and no pi bonds in ~ all. Due to this, the bond formation is quite solid and stable in the instance of carbon tetrafluoride (CF4).

Another way to understand why hybridization is strong in carbon tetrafluoride is, sigma bond are constantly formed by the linear and coaxial overlapping that the atomic orbitals which is more powerful than the lateral overlapping that the pi bond. The molecules comprised of just sigma bonds are extremely reactive i m sorry is why lock are rather responsive to polarity behavior.

Hybridization a photographic representation the determining how the valence electrons of different atoms room bonding to offer rise come a brand-new molecule.

Here, the atomic orbitals of the same power mix and also overlaps to type new degenerated hybrid orbitals that the same energy.

It is a principle of quantum mechanics which says the atom orbitals of similar energy can only get involved in the hybridization procedure which is inclusive the both fully filled and partially to fill orbitals having similar energy.

The mixing and also overlapping that one s and also one p orbital, 2 s and also two ns orbitals, one s and one d orbitals deserve to take place only.

Carbon Tetrafluoride (CF4) Polarity


Polarity is habits by which atoms often tend to separate their electrical charge developing two poles of confident and an unfavorable ends. As result of this separation that charges, a molecule becomes quite responsive come the adjacent atom and tends to one of two people repel or lure it.

In the case of carbon tetrafluoride (CF4), the molecule is uncovered to be nonpolar.

The reason lies in the electronegativity worths of every participating atom, which room carbon and fluorine in this case. Electronegativity is a mathematical means of determining just how strongly an atom will lure the mutual electrons in the direction of itself. The greater the electronegativity value, the bigger will be the force of attraction and vice versa.

The electronegativity worth of carbon and fluorine space 2.5 and 4 where their distinction is 1.5 which is more than 0.4. As per the law, if the electronegativity distinction is much less than 0.4, then the molecule is nonpolar otherwise polar. This method carbon tetrafluoride (CF4) is reflecting an anomaly where the electronegativity difference between the participating atom is bigger than 0.4 whereas that is a nonpolar molecule.

By share rule, if we think about the electronegativity difference blindly, that would median that each of the carbon-fluorine bonds is quite solid and polar. Yet chemistry is complete of exception as proclaimed earlier, that is the tetrahedral framework of the molecule which lug a symmetry within the structure.
