Which of the following reactions will not give pure propane?

Options

  1. AC H 3 C H 2 C l + 2 N a + C l C H 3 → e t h e r
  2. BC H 3 C H 2 C H 2 C O O N a → s o d a l i m e
  3. CC H 3 C H = C H 2 → H 2 / P d
  4. DC H 3 C ≡ C H → H 2 / P d

Correct answer

A. C H 3 C H 2 C l + 2 N a + C l C H 3 → e t h e r

Step-by-step solution

Here in option A reaction will not give pure propane C H 3 C H 2 C l + 2 N a + C l C H 2 C H 3 → d r y e t h e r C H 3 C H 2 C H 2 C H 3 + 2 N a C l C H 3 C l + 2 N a + C l C H 3 → d r y e t h e r C H 3 C H 3 + 2 N a C l C H 3 C H 2 C l + 2 N a + C l C H 3 → d r y e t h e r C H 3 C H 2 C H 3 + N a C l Thus, we get a mixture containing butane, ethane and propane. In rest other reaction pure propane is possible.
