What is hexafluorobenzene used for?
Hexafluorobenzene has been used as a reporter molecule to investigate tissue oxygenation in vivo. It is exceedingly hydrophobic, but exhibits high gas solubility with ideal liquid gas interactions.
Is adamantane toxic?
H319 Causes serious eye irritation. H410 Very toxic to aquatic life with long lasting effects. Precautionary statements P264 Wash contaminated skin thoroughly after handling. P280 Wear protective gloves/ protective clothing/ eye protection/ face protection.
What is the boiling point of c6f6?
hexafluorobenzene Properties 3.7-4.1 °C (lit.) 80-82 °C (lit.)
Does benzene have a higher boiling point than cyclohexane?
Cyclohexane: The melting point of cyclohexane is 6.47 °C and the boiling point is 80.74 °C. Benzene: The melting point of benzene is 5.53 °C and the boiling point is 80.1 °C.
Why is it called adamantane?
Adamantane is the most stable isomer of C10H16. The spatial arrangement of carbon atoms in the adamantane molecule is the same as in the diamond crystal. This similarity led to the name adamantane, which is derived from the Greek adamantinos (relating to steel or diamond). It is a white solid with a camphor-like odor.
What is adamantane used for?
Answer. Amantadine and rimantadine are antiviral drugs in a class of medications known as adamantanes that were once prescribed for influenza treatment or prophylaxis. These medications are active against influenza A viruses, but not influenza B viruses.
What is the boiling point of benzene?
176.2°F (80.1°C)Benzene / Boiling point
Which one is more stable benzene or cyclohexane?
And so benzene is more stable than cyclohexane. At first you might think that the stability is due to the fact that benzene is conjugated, but numerous other experiments have shown that it is even more stable than we would expect. And that extra stability is called aromaticity or aromatic stabilization.
What is the difference between benzene and cyclohexane?
The main difference between cyclohexane and benzene is that cyclohexane contains 12 hydrogen atoms bonded to six carbon atoms, two hydrogen atoms per each carbon atom whereas benzene contains six hydrogen atoms bonded to six carbon atoms, one hydrogen atom per each carbon atom.
Which is the derivative of adamantane?
The adamantane derivatives, amantadine hydrochloride and rimantadine hydrochloride, inhibit viral replication by blocking the proton channel formed by the M2 protein of influenza A viruses.
Can you overdose on amantadine?
An overdose of amantadine can be fatal. Overdose symptoms may include confusion, agitation, behavior changes, hallucinations, severe headache or pounding in your ears, muscle stiffness, problems with balance or walking, trouble breathing, fast heartbeats, or seizure.
What is the freezing point of benzene?
41.9°F (5.5°C)Benzene / Melting point
Why is benzene boiling point lower than water?
Benzene is quite large compared with a water molecule. For benzene to dissolve, it would have to break a significant number of the existing hydrogen bonds between the water molecules.
Which is less reactive benzene or cyclohexane?
Benzene is less reactive with electrophiles than cyclohexene because the delocalised pi system has a lower electron density than the localised pi bond in the C=C double bond. This also means benzene cannot polarise bonds to generate nucleophiles, so reactions may need to take place in the presence of a halogen carrier.
Why is cyclohexane highly stable?
Cyclohexane is the most stable cycloalkane. It is strain-free, meaning neither angle strains nor torsional strains apply, and it shows the same stability as chain alkanes. This special stability is due to a unique conformation it adopts.
Is cyclohexane toxic?
corrosive, highly irritating or toxic substances.
Why is cyclohexane better than benzene?
The main difference between cyclohexane and benzene is that cyclohexane contains twelve hydrogen atoms bonded to six carbon atoms, two hydrogen atoms per each carbon atom whereas benzene contains six hydrogen atoms bonded to six carbon atoms, one hydrogen atom per each carbon atom.
How much is an overdose of amantadine?
When available, serum amantadine levels above 1.5 mg/L have been associated with toxicity.
How much amantadine can you take in a day?
The usual dose is 4.4 to 8.8 milligrams (mg) per kilogram (kg) of body weight per day. The dose is divided evenly and given 2 times a day. However, the dose is usually not more than 150 mg per day.
Is hexafluorobenzene toxic to humans?
Hexafluorobenzene may cause eye and skin irritation, respiratory and digestive tract irritation and can cause central nervous system depression per MSDS. The National Institute for Occupational Safety and Health (NIOSH) lists it in its Registry of Toxic Effects of Chemical Substances as neurotoxicant .
How does hexafluorobenzene react with sodium hydrosulfide?
Most reactions of hexafluorobenzene proceed with displacement of fluoride. One example is its reaction with sodium hydrosulfide to afford pentafluorothiophenol: The reaction of pentafluorophenyl derivatives has been long puzzling for its mechanism. Independent of the substituent, they all exhibit a para directing effect.
Hexafluorobenzene, HFB, C 6F 6, or perfluorobenzene is an organic, aromatic compound. In this derivative of benzene all hydrogen atoms have been replaced by fluorine atoms. The technical uses of the compound are limited, although it is recommended as a solvent in a number of photochemical reactions.
What is the standard state of perfluorobenzene 6?
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).?) 6, or perfluorobenzene is an organic, aromatic compound. In this derivative of benzene all hydrogen atoms have been replaced by fluorine atoms.
