Question

Convert reaction dry ice to acetic acid

Answer 1

Answer:

When dry ice is treated with a Grignard reagent which is chemically called methyl magnesium iodide with formula , in the presence of dry ether it leads to the formation of acetic acid or ethanoic acid. In this process, before formation of the final product, a compound called adduct is formed.

Answer 2

$CO_2(Dry ice) + CH_3MgI$→ $CH_3COOH + Mg(OH)I$

Explanation:

• Solid carbon dioxide is also known as dry ice.
• When a solution of methyl magnesium iodide which is known as the Grignard reagent is treated with solid carbon dioxide that is dry ice in the presence of dry ether.
• The formation of a product is acetic acid or ethanoic acid.
• Before the formation of the final product, a compound called an adduct(magnesium salt of carboxylic acid) is formed.

      $CO_2(Dry ice) + CH_3MgI$(in presence of dry ether)⇒ $CH_3COOMgI$(methyl magnesium iodide)

     $CH_3COOMgI$ ⇒ $CH_3COOH + Mg(OH)I$
