Question

When linolenic acid reacts with hydrogen to form a saturated fatty acid, indicate the stoichiometry of the reaction and the product that is formed. If the stoichiometry of H2 or the product is not integral, enter a fraction (i.e. 3/2).

Answer 1

Answer : The product formed by the given reaction is, oleic acid.

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.

The coefficient tell us about that how many molecules or atoms present in the chemical equation.

When linolenic acid reacts with hydrogen then it react to form a saturated fatty acid that is oleic acid.

The balanced chemical reaction will be:

$C_{18}H_{30}O_2+2H_2\rightarrow C_{18}H_{34}O_2$

By the stoichiometry we can say that, 1 mole of linolenic acid reacts with 2 moles of hydrogen then it react to give 1 mole of oleic acid.

Hence, the product formed by the given reaction is, oleic acid.
