(iv) Alkyl chloride on reduction with zinc and dilute hydrochloric acid gives alkane
Options
- A(i), (iii), (iv)
- B(i), (ii)
- C(i), (ii), (iv)
- 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.
