FAQs on Short Tricks: Haloalkanes & Haloarenes Questions Video Lecture - Chemistry Class 12 - NEET

1. What are haloalkanes and haloarenes?
Ans. Haloalkanes are organic compounds that contain a halogen atom (fluorine, chlorine, bromine, or iodine) attached to an alkane chain. Haloarenes, on the other hand, are organic compounds that contain a halogen atom attached to an aromatic ring.
2. How are haloalkanes and haloarenes named?
Ans. Haloalkanes are named by replacing the -e ending of the corresponding alkane with the suffix -o and adding the name of the halogen as a prefix. For example, chloroethane is the name of the haloalkane derived from ethane with a chlorine atom attached. Haloarenes are named by using the prefixes fluoro-, chloro-, bromo-, or iodo- to indicate the halogen atom attached to the aromatic ring.
3. What are some important reactions of haloalkanes and haloarenes?
Ans. Some important reactions of haloalkanes include nucleophilic substitution, elimination, and rearrangement reactions. Haloarenes, on the other hand, undergo nucleophilic aromatic substitution reactions due to the presence of the aromatic ring.
4. How do haloalkanes and haloarenes affect the environment?
Ans. Haloalkanes and haloarenes are often used as solvents, pesticides, and flame retardants, among other applications. However, they can be harmful to the environment due to their persistence and potential toxicity. Chlorofluorocarbons (CFCs), for example, have been implicated in ozone depletion.
5. What are some examples of haloalkanes and haloarenes?
Ans. Some examples of haloalkanes include chloroform (CHCl3), dichloromethane (CH2Cl2), and chlorobenzene (C6H5Cl). Examples of haloarenes include bromobenzene (C6H5Br), chlorobenzene (C6H5Cl), and iodobenzene (C6H5I).
