FAQs on Integer Answer Type Questions: Haloalkanes & Haloarenes - JEE Advanced

1. What are haloalkanes?
Ans. Haloalkanes are organic compounds that contain halogen atoms (such as chlorine, bromine, or iodine) bonded to carbon atoms. They are commonly used as solvents, starting materials in organic synthesis, and refrigerants.
2. How are haloalkanes classified?
Ans. Haloalkanes can be classified based on the number of halogen atoms attached to the carbon atom. They can be mono-halogenated (one halogen atom), di-halogenated (two halogen atoms), or polyhalogenated (more than two halogen atoms).
3. What are the properties of haloalkanes?
Ans. Haloalkanes have higher boiling points compared to their corresponding alkanes due to the presence of polar covalent bonds. They are generally insoluble in water but soluble in nonpolar solvents. Haloalkanes exhibit reactivity due to the polarization of the carbon-halogen bond.
4. How are haloalkanes prepared?
Ans. Haloalkanes can be prepared through various methods such as the addition of halogens to alkenes, the reaction of alcohols with hydrogen halides, and the substitution of hydrogen atoms in alkanes with halogens.
5. What are haloarenes?
Ans. Haloarenes are organic compounds that contain halogen atoms bonded to an aromatic ring. They are similar to haloalkanes but have halogen atoms attached to the carbon atoms in an aromatic system. Haloarenes are used in pharmaceuticals, agrochemicals, and dyes manufacturing.
