Question

Which of the following statements is true for the alkyl halide?

• A. Alkyl halides are formed by the replacement of hydrogen atom in hydrocarbon by halogen atom
• B. Alkyl halide has no polar bond
• C. In haloalkane, halogen is attached to $s{p}^2$-hybridised carbon atom
• D. None of the haloalkane are found in nature

Answer 1

Answer: (A)

The replacement of hydrogen atom in a hydrocarbon, aliphatic or aromatic, by halogen atom(s) results in the formation of alkyl halide (haloalkane) or aryl halide (haloarene). Haloalkanes contain halogen atom(s) attached to the $s{p}^3$-hybridised carbon atom of an alkyl group. The $C-X$ bond in the haloalkanes is polar.
