Draw the isomers of a compound with the molecule formula C4H4O4. Also state the isomerism exhibited by them.
1 answer:
cis-2- butene-1,4-dioic acid and trans-2- butene-1,4-dioic acid are the 2 isomers with the molecular formula C₄H₄O₄.
<u>Explanation:</u>
Isomers are the structures having the same molecular formula but their is a difference in their structural formula and this concept is known as isomerism.
Here we have the molecular formula C₄H₄O₄ and it may be dicarboxylic acid and it may be exist as geometrical isomers as cis-2- butene-1,4-dioic acid and trans-2- butene-1,4-dioic acid.
The isomers are given.

<u>Answer:</u> The limiting reagent in the given chemical reaction is carbon metal.
<u>Explanation:</u>
Excess reagent is defined as the reagent which is present in large amount in a chemical reaction.
Limiting reagent is defined as the reagent which is present in small amount in a chemical reaction. Formation of product depends on the limiting reagent.
To calculate the number of moles, we use the equation:
.....(1)
- <u>For sodium sulfate:</u>
Given mass of sodium sulfate = 16.29 g
Molar mass of sodium sulfate = 142 g/mol
Putting values in equation 1, we get:
- <u>For carbon:</u>
Given mass of carbon = 3.697 g
Molar mass of carbon = 12 g/mol
Putting values in equation 1, we get:
For the given chemical reaction:
By Stoichiometry of the reaction:
4 moles of carbon reacts with 1 mole of sodium sulfate
So, 0.31 moles of carbon will react with = of sodium sulfate
As, given amount of sodium sulfate is more than the required amount. So, it is considered as an excess reagent.
Thus, carbon metal is considered as a limiting reagent because it limits the formation of product.
Hence, the limiting reagent in the given chemical reaction is carbon metal.
