A chemical reaction in which addition of hydrogen takes place in
Answer to Problem 75A
Three hydrogen molecules are required for hydrogenation of 1 mole of linolenic acid.
The balanced chemical equation is:
Explanation of Solution
Molecular formula of linolenic acid =
Condensed structural formula of linolenic acid:
The reaction between linolenic acid and hydrogen molecule is:
Also,
Now, to balance the above equation, hydrogen atoms must be equal on both sides of reaction
Thus, coefficient three should be placed before hydrogen molecule.
Hence, the balanced chemical equation is:
According to above reaction, three hydrogen molecules are required for hydrogenation of 1 mole of linolenic acid.
