Given below are two statements: Statement I: Methane can be prepared by decarboxylation of sodium ethanoate, Kolbe's electrolysis of sodium acetate and reaction of CH ₃ MgBr with water. Statement II: Methane cannot be prepared from unsaturated hydrocarbons and by Wurtz reaction. In the light of the above statements, choose the correct answer from the options given below

Options

  1. ABoth Statement I and Statement II are true
  2. BBoth Statement I and Statement II are false
  3. CStatement I is true but Statement II is false
  4. DStatement I is false but Statement II is true

Correct answer

D. Statement I is false but Statement II is true

Step-by-step solution

Statement I is false because Kolbe's electrolysis of sodium acetate produces ethane, not methane. The reaction is: 2 CH ₃ COONa + 2 H ₂ O Electrolysis CH ₃- CH ₃ + 2 CO ₂ + H ₂ + 2 NaOH . Decarboxylation of sodium ethanoate and the reaction of CH ₃ MgBr with water do produce methane. Statement II is true because the simplest unsaturated hydrocarbon is ethene ( C ₂ H ₄ ), which upon hydrogenation yields ethane, meaning methane cannot be prepared from unsaturated hydrocarbons. Additionally, the Wurtz reaction involve
