How can quarternary alkanes be produced from lower alkyl halides?
Quarternary alkanes can be produced from lower alkyl halides through carbocations.
What is the energy released in the combustion of hexane?
Hexane - lower heating value at 15,4 0C: 44,752 MJ/kg (3 856,66 kg/mol)
Would you expect hexane to be soluble in water?
The density of cyclohexane is lower than that of water (0.779 g/mL vs. 1.0 g/mL respectively), so it will float on top of water.
Why would we not crack octane industrially?
Octane is very useful the way it comes, and the lower alkanes you could crack octane into are plentiful. Cracking is a good technique for converting bitumen into an alkane that fuel can be made from, but you can make fuel (specifically gasoline) from octane.
What determines whether a compound will be more soluble in hexane or in H2O?
Calcium Carbonate Some compounds are amphipathic. Water is a polar solvent and hexane is a nonpolar solvent. For a compound to dissolve in both, it would need to posses some nonpolar properties and some polar properties.
How can quarternary alkanes be produced from lower alkyl halides?
Quarternary alkanes can be produced from lower alkyl halides through carbocations.
Which has the highest boiling point hexane or pentane?
Octane. The boiling point of straight-chain alkanes increases within its homologous series (meaning methane has a lower boiling point than ethane, which is lower than propane, etc). Hexane : Boiling Point 69 o C Octane : Boiling Point 125.5 o C
What is the energy released in the combustion of hexane?
Hexane - lower heating value at 15,4 0C: 44,752 MJ/kg (3 856,66 kg/mol)
How can you prepare 13-dibromopropane in the laboratory from lower alkanes or alkyl halides?
You can prepare 13-dibromopropane in the laboratory from lower alkanes or alkyl halides using HBr in the presence of peroxide.
What alkanes are gases at room temperature?
Lower alkanes are gases. As the number of carbon increases they are liquids and even solids.
Why is it impossible to crack the middle of your lower back?
It's not impossible
Why does isomerisation turn straight chain alkanes into alkanes with lower boiling temperature?
Isomerisation causes straight chain alkanes to become branched alkanes which prevents the chains from moving to close proximities of each other. This reduces the van der Waal's intermolecular forces between chains so less energy is needed to overcome the forces and thus a lower boiling point.
Would you expect hexane to be soluble in water?
The density of cyclohexane is lower than that of water (0.779 g/mL vs. 1.0 g/mL respectively), so it will float on top of water.
Why hexane is used as solvent in soxhlate apparatus?
Hexane is used because it is relatively unreactive. Actually, any solvent that is unreactive can be used. However, the general criteria to be employed in choosing a solvent are 1) its solubility/polarity to the mixture/solute, 2) its boiling point is lower than the solute/analyte and 3) it is unreactive.
What is the boiling point of hexane?
Think in terms of room temperature. Hexane is a liquid that is flammable, but is used in cleaning solvents and stuff like around the garage. Propane is the gas that comes in a steel bottle that you use for gas stoves and barbeque grills. So if you let propane out into the room its a gas and so it already past its boiling point. So the boiling point of Hexane is hotter than room temperature and the boiling point of propane is lower than room temperature. The actual numbers are 69 C and -42 C.
Is hexane a solid liquid or gas?
It has to do with intermolecular forces holding the molecules together. Both ethane and hexane are hydrocarbons, so the only intermolecular forces at work are dispersion forces. There are more/greater dispersion forces in hexane than in ethane because there are more carbon atoms. This stronger force makes it harder for the molecules to became a gas and keeps them as a liquid until heat is applied, then it can vaporize.
On Base percentage lower than batting average?
its nearly impossible to have a lower on base percentage then your batting average
