When acetylene is passed through red hot iron tube, compound X is formed. Which one of the following reactions will yield X as the major product?

Options

  1. AC ₆ H ₅ OH + Zn Distillation
  2. BC ₆ H ₅ SO ₃ H + NaHCO ₃
  3. CC ₆ H ₁₂+3 H ₂ Ni
  4. DC ₆ H ₅ Cl + H ₂ O

Correct answer

A. C ₆ H ₅ OH + Zn Distillation

Step-by-step solution

When acetylene is passed through red hot iron tube, benzene is formed as 3 C ₂ H ₂ red hot tube C ₆ H ₆(X) Reaction (a) also gives C ₆ H ₆ (or X ) as C ₆ H ₅ OH + Zn distillation C ₆ H ₆+ ZnO
