NEET Chemistry Haloalkanes and Haloarenes – Properties, Reactions & Applications

Haloalkanes and Haloarenes are organic compounds in which one or more hydrogen atoms are replaced by halogen atoms such as fluorine, chlorine, bromine, or iodine. These compounds are widely used in organic synthesis and industrial applications.

This chapter is an important part of NEET Chemistry and frequently appears in reaction-based and conceptual questions.

What are Haloalkanes?

Haloalkanes, also known as alkyl halides, are compounds in which a halogen atom is attached to an alkyl group. They serve as important intermediates in organic reactions.

What are Haloarenes?

Haloarenes, also known as aryl halides, are compounds in which a halogen atom is directly attached to an aromatic ring. Their chemical behavior differs from that of haloalkanes due to the aromatic structure.
