2CH3,COOH+xCa→ Ca (OCOCH3)2 +H2O. Calculate value of "x".
Correct answer: A. 1
- A. 1
- B. 3
- C. 2
- D. 4
Explanation
Option A is correct. Ca exists in the free form as Ca+2 so on reaction it has tendency to give two electrons to make two bonds.Since 2 moles of carboxylic acid are used so they shoul need only one mole of Ca+2 because Ca+2 itself has tendency to mae two bonds.2CH3COOH+1Ca+2 → Ca-(OCOCH3)2Only one mole of Ca is needed Hence the value of x is 1.

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.
