Question

Match the structures of compounds given in Column I with the classes of compounds given in Column II.
  Column I   Column II
$(i)$ $\text{CH}_3-\text{CH}-\text{CH}_3\\ \ \ \ \ \ \ \ \ \ \ \ \ \ |\\ \ \ \ \ \ \ \ \ \ \ \ \ \text{X}$ $(a)$ Aryl halide
$(ii)$ $\text{CH}_2==\text{CH}-\text{CH}_2-\text{X}$ $(b)$ Alkyl halide
$(iii)$ $(c)$ Vinyl halide
$(iv)$ $\text{CH}_2==\text{CH}-\text{X}$ $(d)$ Allyl halide

Answer

  Column I   Column II
(i) $\text{CH}_3-\text{CH}-\text{CH}_3\\ \ \ \ \ \ \ \ \ \ \ \ \ \ |\\ \ \ \ \ \ \ \ \ \ \ \ \ \text{X}$ (b) Alkyl halide
(ii) $\text{CH}_2==\text{CH}-\text{CH}_2-\text{X}$ (d) Allyl halide
(iii) hight: 69px; width: 49px; (a) Aryl halide
(iv) $\text{CH}_2==\text{CH}-\text{X}$ (c) Vinyl halide
Explanation: The conditions for different classes of haloalkanes or haloarenes are satisfied as mentioned below,
  1. Alkyl halides: In alkyl halides, the halogen atom is bonded to an alkyl group $(R)$
  2. Allyl halides: These are compounds in which halogen atom iis bonded to an $sp^3-$ hybrdised carbon atom next to carbo-carbon double bond. $(C=C)$ i.e. to an allylic carbon.
  3. Vinyl halides: These are compounds in which the halogen atom is bonded to an $sp^2-$hybridised carbon atom of carbon-carbon double bond $(C=C).$
  4. Aryl halides: These are the compounds in which the halogen atom is bonded to the $sp^2$ hybridised carbon atom of an aromatic ring.
