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.
How do psychical and chemical properties of halogens compare with those of the inert gas?
At room temperature the lighter halogens, F, Cl are diatomic gases, Br is a liquid, I is a solid. All of the halogens are colored and toxic. The noble gases are all colorless odorless non chemically toxic monoatomic gases. (Radon is radioactive).
Is the group halogens in a periodic table reactive?
Very much so. The only group that isn't reactive is the Noble gases, however even some noble gases will react under the right 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.
Halogens that are gases at room temperature and pressure?
The halogens that are gases at room temperature and pressure are fluorine and chlorine.
What is the Sulfonation process to produce dodecyl benzene sulfonic acid?
The sulfonation process to produce dodecyl benzene sulfonic acid involves reacting dodecyl benzene with a sulfonating agent, such as sulfur trioxide or chlorosulfonic acid, to introduce a sulfonic acid group onto the benzene ring. The reaction typically takes place under controlled conditions of temperature and pressure to ensure high yield and purity of the desired product. The dodecyl benzene sulfonic acid produced is an important surfactant used in various industries.
