What reagent converts sodiumethanoate to methane?

To convert sodium ethanoate (also known as sodium acetate) to methane, you would need to use a combination of reagents and a series of chemical reactions.

Step 1: Conversion of sodium ethanoate to acetic acid
To convert sodium ethanoate to acetic acid, you need to add a strong acid, such as hydrochloric acid (HCl). The reaction can be represented as follows:

CH3COONa + HCl -> CH3COOH + NaCl

Step 2: Conversion of acetic acid to acetyl chloride
To convert acetic acid to acetyl chloride, you need to react it with thionyl chloride (SOCl2). The reaction can be represented as follows:

CH3COOH + SOCl2 -> CH3C(O)Cl + SO2 + HCl

Step 3: Conversion of acetyl chloride to methane
To convert acetyl chloride to methane, you need to react it with lithium aluminum hydride (LiAlH4). The reaction can be represented as follows:

CH3C(O)Cl + 4 LiAlH4 -> CH4 + LiCl + AlCl3 + 4 LiOH

In this reaction, LiAlH4 acts as a reducing agent, which donates four hydride ions (H-) to the acetyl chloride, resulting in the formation of methane.
