When a new synthetic method is developed, it is applied to a series of compounds to explore its utility. 4-Fluorophenylacetonitr
1 answer:
Answer:
See explanation
Explanation:
Since the -CH3CN and the -F are in 1,4 position, then the synthesis started with flourobenzene. This has to be because -F is ortho-para directing in nucleophilic substitution.
The next step is the Friedel craft alkylation of the substrate. The alkyl group is directed to the para position by the -F.
Bromination using NBS yields an alkyl bromide that undergoes SN2 substitution to yield the target compound.

Double displacement reaction is defined as the reaction in which exchange of ions takes place.
When sodium permanganate reacts with iron (III) chloride, it leads to the production of sodium chloride and iron (III) permanganate.
The chemical equation for the reaction of sodium permanganate and iron (III) chloride follows:
By Stoichiometry of the reaction:
3 moles of aqueous solution of sodium permanganate reacts with 1 mole of aqueous solution of iron (III) chloride to produce 1 mole of solid iron permanganate and 3 moles of aqueous solution of sodium chloride
Hence, the balanced chemical equation is written above.

<u>Answer:</u> The percentage yield of water is 9.5 %
<u>Explanation:</u>
We are given:
Moles of hydrogen = 14 moles
Moles of oxygen = 10 moles
The chemical equation for the formation of water from hydrogen and oxygen follows:
By Stoichiometry of the reaction:
2 moles of hydrogen gas reacts with 1 mole of oxygen gas
So, 14 moles of hydrogen gas will react with = of oxygen gas
As, given amount of oxygen gas is more than the required amount. So, it is considered as an excess reagent
Thus, hydrogen gas is considered as a limiting reagent because it limits the formation of product.
By Stoichiometry of the reaction:
2 moles of hydrogen gas produces 2 moles of water
So, 14 moles of hydrogen gas will produce = of water
To calculate the percentage yield of water, we use the equation:
Experimental yield of water = 1.33 moles
Theoretical yield of water = 14 moles
Putting values in above equation, we get:
Hence, the percent yield of the water is 9.5 %.
