Consider the following reaction:CH3COOH + Mg→What product will form?
Correct answer: B. Magnesium acetate
- A. Magnesium formate
- B. Magnesium acetate
- C. Magnesium ion
- D. Carboxylate ion
Explanation
In the equation given in the above reaction acetic acid or ethanoic acid i.e. CH3COOH reacts with Magnesium Mg so it Mg will come in place of H CH3COO- is called acetate ion and as Mg attaches with O- it forms salt called magnesium acetate with evolution of H2 gas. 2CH3COOH + Mg -> 2CH3COOMg + H2

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
