(iv) Alkyl chloride on reduction with zinc and dilute hydrochloric acid gives alkane

Options

  1. A(i), (iii), (iv)
  2. B(i), (ii)
  3. C(i), (ii), (iv)
  4. D(iii), (iv)

Correct answer

C. (i), (ii), (iv)

Step-by-step solution

(i) Petrol and CNG operated automobiles causes less pollution. (ii) Alkane having tertiary hydrogen therefore oxidise in presence of KMnO ₄ into alcohol. (iv) Alkyl halide on reduction with zinc and dilute HCl gives alkane.
