CCL4 Structure and Nature
CCL4 common name compound has the right usage, and this has been phased out by several governments on the basis of its toxicity. Inhaling a large amount of the component can highly damage vital human organs. It is extremely detrimental to the human liver and kidneys. Carbon tetrachloride can have an adverse impact on the CNS or the Central Nervous System. However, the kind of extensive human exposure to the same can cause sudden death and dismay. The same is also extensively used as the precursor to chlorofluorocarbons.
Structuring of the Compound
On researching, you can get to know in detail the CCL4 common name compound. Due to various environmental concerns, there has been a sudden decline in the manufacturing of the compound since the 1980s. Exposure and contact with the same can cause centrilobular hepatic necrosis. Within the human body, the compound has been highly metabolized in the form of trichloromethyl radical. This is highly reactive in nature. The reaction of the compound can cause this kind of hepatocellular damage. CCL4 is known for having the molecular structure of geometries. It is the central carbon atom, and it is bonded to the four basic chlorine atoms.
There are several details to help you have an idea about the CCL4 Structure. It is highly important to know that four chlorine atoms are systematically positioned at each of the corners at the point of the central carbon atom present in the CCL4 molecule. It is the bonding between the carbon atom and the version of the chlorine atoms, and these are covalent in the real sense. In consequence, the molecular geometry is clear regarding the specific compound.
What is CCL4?
CCL4 comes with some of the best chemical and physical properties. The molar mass of ccl4 is 153.81 grams per mole. Under the right conditions, one can find the compound in the liquid state. The compound is a colorless solution, and it is known for its sweet smell. The compound has a density in the liquid state, and it is 1.5867 grams per cubic centimeter. It is a melting point of -22.93oC, and the boiling point of the same is 76.72oC. CCL4 is not completely soluble in water. At the temperature of twenty-five-degree centigrade, the solubility of CCL4 in water is approximately I gram per liter. However, it is notable that the same compound is highly soluble in some of the major organic solvents like chloroform, benzene, alcohols, ethers, and formic acid.
CCL4 Dipole Moment
CCL4 has the polar molecular result, and it happens due to the unequal sharing of the case of the valence electrons. In the case of molecular states like carbon tetrachloride, the bonds are rightly distributed, and they are even discarded as required. Thus, one cannot find any sure dipole moment, and the compound is extremely non-polar in existence. The carbon tetrachloride crystallizes in the form of a monoclinic crystalline lattice. The thermal capacity of the same is 132.6 Joules per mole-Kelvin, and it has the standard molar entropy, and that is 214.42 Joules per mole-Kelvin.
Conclusion
CCL4 stands for carbon tetrachloride, and it is the molecule formed with the carbon combination in connection with the four chlorine atoms. The carbon atom, in this case, has four electrons in the external electrical shell. Carbon is the central atom here, and CCL4 has the capacity to share the four of the electrons along with each of the four chlorine atoms, and here there are none of the unshared parts of the various electrons.
FAQs on Carbon Tetrachloride CCl4 Structure Properties and Applications
1. What is CCl4 in chemistry?
CCl4 is carbon tetrachloride, a covalent compound composed of one carbon atom bonded to four chlorine atoms. It has the molecular formula CCl4 and belongs to the class of haloalkanes (alkyl halides).
- It is a colorless, non-flammable liquid.
- It has a sweet odor.
- It was historically used as a solvent and fire extinguisher fluid.
2. What is the structure and geometry of CCl4?
CCl4 has a tetrahedral geometry with bond angles of approximately 109.5°. According to VSEPR theory:
- The central carbon forms four single covalent bonds with chlorine atoms.
- There are no lone pairs on the central carbon.
- The molecular shape is symmetrical and three-dimensional.
3. Is CCl4 polar or nonpolar?
CCl4 is a nonpolar molecule despite having polar C–Cl bonds. Although each C–Cl bond is polar due to electronegativity differences:
- The tetrahedral geometry is perfectly symmetrical.
- The bond dipoles cancel each other out.
- The net dipole moment is zero.
4. What is the hybridization of carbon in CCl4?
The carbon atom in CCl4 is sp3 hybridized. Carbon forms four sigma (σ) bonds with chlorine atoms:
- One 2s and three 2p orbitals hybridize to form four sp3 orbitals.
- Each sp3 orbital overlaps with a chlorine p orbital.
- This results in a tetrahedral arrangement.
5. What are the physical properties of carbon tetrachloride?
Carbon tetrachloride is a dense, nonpolar liquid with a relatively high boiling point. Key physical properties include:
- Molar mass: 153.82 g/mol
- Boiling point: about 76.7°C
- Density: about 1.59 g/cm3 at 20°C
- Insoluble in water but soluble in nonpolar solvents
6. How is CCl4 prepared industrially?
CCl4 is prepared industrially by the chlorination of methane or other hydrocarbons. A simplified reaction is:
CH4(g) + 4Cl2(g) → CCl4(l) + 4HCl(g)
- This reaction occurs under UV light or high temperature.
- It proceeds through a free radical substitution mechanism.
- Multiple chlorinated products may form.
7. Why is CCl4 not soluble in water?
CCl4 is not soluble in water because it is nonpolar while water is polar. According to the principle “like dissolves like”:
- Polar solvents dissolve polar substances.
- Nonpolar substances dissolve in nonpolar solvents.
- No strong intermolecular forces form between CCl4 and H2O.
8. What are the uses of carbon tetrachloride?
Carbon tetrachloride has been used as a solvent and in the manufacture of refrigerants and chemicals. Common historical and industrial uses include:
- Solvent for fats, oils, and resins
- Production of chlorofluorocarbons (CFCs)
- Laboratory reagent
9. Is CCl4 toxic or dangerous?
Yes, CCl4 is highly toxic and can cause serious liver and kidney damage. Key safety concerns include:
- Toxic if inhaled or ingested
- Can damage the central nervous system
- Contributes to ozone layer depletion
10. What is the difference between CCl4 and CHCl3?
CCl4 (carbon tetrachloride) is nonpolar, while CHCl3 (chloroform) is slightly polar due to asymmetry. The main differences are:
- CCl4: symmetrical tetrahedral structure, zero dipole moment.
- CHCl3: one hydrogen and three chlorine atoms create a net dipole.
- CHCl3 has different boiling point and solubility behavior.
