What is the name of the compound with the formula CBr4 ?
The Correct Answer and Explanation is :
The compound with the formula CBr₄ is called carbon tetrabromide.
Explanation:
Carbon tetrabromide (CBr₄) is a chemical compound composed of one carbon (C) atom bonded to four bromine (Br) atoms. This compound belongs to the family of halides, where a halogen (in this case, bromine) is bonded to a carbon atom.
Carbon tetrabromide is structurally similar to carbon tetrachloride (CCl₄), where chlorine atoms replace the bromine atoms. Both compounds share similarities in their tetrahedral molecular geometry, as the central carbon atom forms four single bonds with the surrounding bromine atoms. The molecule is nonpolar due to its symmetrical shape, which ensures the cancellation of any dipole moments.
Physical Properties:
Carbon tetrabromide is a colorless, odorless, and dense liquid at room temperature. Its density is higher than that of water, and it has a relatively low melting point of about 93°C. It is insoluble in water but soluble in organic solvents such as alcohol and ether.
Chemical Properties:
CBr₄ is relatively stable and does not readily react under normal conditions. However, it can decompose under extreme conditions, producing bromine gas (Br₂) and carbon. Additionally, it can act as a source of bromine in chemical reactions.
Historically, carbon tetrabromide was used in fire extinguishers and as a solvent in organic chemistry, although its use has declined due to its toxicity and potential environmental impact, similar to carbon tetrachloride.
The compound is considered toxic when inhaled or ingested, and exposure may cause damage to the liver and kidneys. For this reason, precautions should be taken when handling this compound in laboratory or industrial settings.
In summary, carbon tetrabromide (CBr₄) is a halogenated organic compound with notable applications in the past but limited current use due to health and environmental concerns.
