Question

An alkaline (A)C₅H₁₂ on chlorination at 300°C gives a mixture of four different monochlorinated derivatives, (B), (C), (D), and (E). Two of these derivatives give the same stable alkene (F) on dehydrohalogenation. On oxidation with hot alkaline KMnO₄ followed by acidification, (F) gives two products (G) and (H). Give the structures of (A) to (H) with porper reasoning.

Answer 1

i. Alkane (A) C₅ H₁₂ on chlorination gives four monochlroro products and thus (A) is isopentane.
