Alkyl Halide Examples

Alkyl halides are compounds that contain halogens as one of their constituents along with alkanes. In alkane, when one or more hydrogen atoms get substituted by halogen atoms it is termed an alkyl halide. They also called as Haloalkane.

Alkyl halides are classified as

On account of several carbon atoms having bonded with the carbon atom, which is attached to the halogen atom, alkyl halides are classified as primary, secondary, tertiary alkyl halides.

Primary alkyl halides (1°)

When one carbon atom had a bond with the carbon atom which is attached to the halogen atom it is known as Primary alkyl halide or 1° alkyl halide.

Usually primary alkyl halides undergo S_N2 reaction mechanism.

Secondary alkyl halides (2°)

When two carbon atoms had a bond with the carbon atom which is attached to the halogen atom it is known as Secondary alkyl halides or 2° alkyl halides.

Secondary alkyl halides undergo both S_N1 and S_N2 reaction mechanisms.

Tertiary alkyl halides (3°)

When three carbon atoms had a bond with the carbon atom which is attached to the halogen atom it is known as Tertiary alkyl halides or 3° alkyl halides.

Tertiary alkyl halide undergo S_N1 reaction mechanism.
