How can alkanes be described?
Alkanes are hydrocarbons with only single bonds between carbon atoms, making them saturated hydrocarbons. They are colorless, odorless, and nonpolar molecules that are relatively unreactive under normal conditions. The physical properties of alkanes, such as boiling point and solubility, increase with increasing molecular weight.
How do physical and chemical properties of the halogens compare with those of the noble gas?
the noble gases atre very unreactive and are oderless, tasteless and clourless under standard conditions whereas the group 7 halogens are a very reactive group.
Why brnzene doesnt react with Br2 in presence of CCl4?
Benzene does not react with Br₂ in the presence of CCl₄ because the conditions do not favor the electrophilic bromination of benzene. In this scenario, CCl₄ acts as a non-polar solvent that does not promote the formation of the necessary bromonium ion. Additionally, benzene's stable aromatic system resists reactions that require the disruption of its π-electron cloud. As a result, without a catalyst like FeBr₃ to facilitate the reaction, benzene remains inert to bromine under these conditions.
Why is it impossible to sulphonate alkanes lower than hexane with oleum?
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.
What and Why is more volatile benzene or acetone?
Benzene is generally more volatile than acetone due to its lower boiling point and higher vapor pressure at room temperature. Benzene has a boiling point of about 80.1°C, while acetone's is around 56.5°C; however, the volatility is also influenced by molecular structure and intermolecular forces. Benzene's non-polar structure leads to weaker van der Waals forces compared to the polar nature of acetone, resulting in higher volatility for benzene. Therefore, benzene evaporates more readily under similar conditions.

Why is there no reaction between potassium permanganate and alkanes?
Potassium permanganate is a strong oxidizing agent, but alkanes are not easily oxidized due to their stable C-C and C-H bonds. As a result, there is no reaction between potassium permanganate and alkanes under normal conditions.
Equation for benzene plus KMnO4?
Benzene does not react directly with potassium permanganate (KMnO4) under normal conditions. Benzene is a stable aromatic compound and does not undergo typical alkene or alkane reactions with oxidizing agents like KMnO4.
What is the critical point of benzene?
The critical point of benzene is the temperature of 562.0°C and pressure of 48.9 atm. At this point, benzene exists as a supercritical fluid, demonstrating properties of both a liquid and a gas. Physically, it marks the highest attainable state for benzene under specific conditions of temperature and pressure.
What coloure is bromine?
Bromine is a dark brown liquid element belonging to the halogens.

Is silicon flammable?
No, silicon is not flammable because it does not react with oxygen at typical environmental temperatures. However, silicon can react with halogens under suitable conditions.
Is the non metal lodine strongly reactive?
Iodine is not considered strongly reactive. It is a non-metal element that is relatively unreactive under normal conditions. It can react with certain elements under specific conditions, but its reactivity is generally lower compared to other non-metals like chlorine or fluorine.
