Sulphonation of alkanes involves the substitution of a hydrogen atom with a sulfonyl group. Alkanes lower than hexane, such as methane and ethane, are too unreactive due to their saturated nature and lack of functional groups that can stabilize a carbocation intermediate. The reaction typically requires higher temperatures or more reactive substrates, which makes it impractical for lower alkanes to undergo sulphonation with oleum. Consequently, these smaller alkanes do not react significantly under the conditions necessary for sulphonation.

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?
The energy released in the combustion of hexane is approximately 46.8 megajoules per gram of hexane combusted.
Is ice more dense than hexane?
No, ice is not more dense than hexane. Ice has a density of about 0.92 g/cm³, while hexane has a density of approximately 0.66 g/cm³. This lower density of hexane means that ice will float on hexane when the two are combined.
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.
The difference of hexane and butanol in boiling point?
Hexane has a lower boiling point compared to butanol. The difference in boiling points arises from the difference in molecular weights, functional groups, and intermolecular forces present in the two compounds. Butanol, with its hydroxyl group, exhibits stronger hydrogen bonding interactions, leading to a higher boiling point compared to hexane.
How can quarternary alkanes be produced from lower alkyl halides?

What is the energy released in the combustion of hexane?
The energy released in the combustion of hexane is approximately 46.8 megajoules per gram of hexane combusted.
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.
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
Is ice more dense than hexane?
No, ice is not more dense than hexane. Ice has a density of about 0.92 g/cm³, while hexane has a density of approximately 0.66 g/cm³. This lower density of hexane means that ice will float on hexane when the two are combined.
Why was hexane eluted earlier than toluene?
Hexane has a lower boiling point than toluene, so it is less strongly retained on the stationary phase of the chromatography column. This leads to hexane being eluted earlier than toluene during the separation process.
What alkanes are gases at room temperature?
Examples of alkanes that are gases at room temperature include methane (CH4), ethane (C2H6), and propane (C3H8).
What are the differences in the properties and uses of ether and hexane?
Ether and hexane are both organic compounds, but they have different properties and uses. Ether is a volatile liquid with a sweet smell, commonly used as a solvent and anesthetic. Hexane is a nonpolar liquid with a strong odor, often used as a solvent in laboratories and as a cleaning agent. Ether is more flammable and has a lower boiling point than hexane.
What is the Disadvantage of using hexane as an extracting solvent compared to petroleum ether and an alcohol?
One disadvantage of using hexane as an extracting solvent compared to petroleum ether and alcohol is that hexane is more toxic and poses a higher risk to human health and the environment. Additionally, hexane has a lower boiling point than petroleum ether, making it more flammable. Finally, hexane has a higher cost compared to petroleum ether and some alcohols commonly used as extracting solvents.
How do you remove benzene from hexane?
Fractional distillation in a distillation column will remove benzene from hexane. The vapor-liquid-equilibrium data indicate that depending on initial and desired concentrations, multiple theoretical stages will likely be needed. See also vapor liquid equilibrium chart for benzene and hexane.
Which has greater volume 10g of hexane or 10g of toluene?
To calculate volume out of mass you'll need the density figures of both compounds:Hexane 0.6548 g/mLToluene 0.8669 g/mL (20 °C)Volume of 10.0 grams: (divide mass (g) by density (g/mL) )Hexane 10 g / 0.6548 g/mL = 15.27 mLToluene 10 g / 0.8669 g/mL = 11.54 mLSo, the volume of (10 g) hexane is 32% greaterthan of the same amount of toluene
