Question

Choose the correct answer among the alternatives given :
Haloalkanes contain halogen atom(s) attached to the $s{p}^3$ hybridised carbon atom of an alkyl group. Identify haloalkane from the following compounds.

(i) 2-Bromopentane
(ii) Vinyl chloride
(iii) 2-Chloroacetophenone
(iv) Trichloromethane

• A. Only (ii)
• B. (ii) and (iv) only
• C. (i) and (iv) only
• D. (i), (ii) and (iii) only

Answer 1

Answer: (C)

(i) and (iv) only

When an hydrogen atom in an aliphatic or aromatic hydrocarbon is replaced by halogen atoms then the compounds are termed as haloalkanes. It is attached to an $s{p}^3$ hybridized atom of an alkyl group. Haloalkanes haves all the chemical bonds attached to the carbon atoms in single bonds and the halogen atom is attached to a single carbon atom.

Examples ; 2- Bromopentane and Trichloromethane.
