Acetylene can be obtained by the reaction?

Options

  1. AH C O O K → E l e c t r o l y s i s
  2. BC H I 3 + A g → ∆
  3. CC H 3 C H 2 O H → C o n c . H 2 S O 4 443 K
  4. DB e 2 C + H 2 O →

Correct answer

B. C H I 3 + A g → ∆

Step-by-step solution

Iodoform and Silver (Ag) undergo dehalogenation reaction to produce acetylene. (A) H C O O K + H 2 O → ∆ H 2 + C O 2 + K O H (B) 2 CHI 3 Iodoform + 6 Ag Silver → ∆ CH ≡ CH Acetylene + 6 AgI (C) CH 3 CH 2 OH → Conc . H 2 SO 4 443 K CH 2 = CH 2 ethylene + H 2 O (D) Be 2 C + H 2 O → CH 4 Methane
