Question

What is the structural formula of fumaric acid ?
A.
B.
C.
D.

Answer 1

Fumaric acid is an organic compound having the chemical formula as $H{{O}_{2}}CCH=CHC{{O}_{2}}H$ and it is the trans isomer of the butenedioic acid. So, by using the chemical formula you can easily find out the structural formula of the fumaric acid.

Complete step-by-step answer: First of all let’s discuss the fumaric acid. Fumaric acid is a white solid organic compound which has the molecular chemical formula as $H{{O}_{2}}CCH=CHC{{O}_{2}}H$ . so, from the chemical formula, it is clear that it is the trans isomer of butenedioic acid band its IUPAC name is E-butenedioic acid.
Fumaric acid is widely found in nature and it has fruit-like taste. The salts and the esters of the fumaric acid are commonly known as the fumarates.
The molar mass of fumaric acid is 116.07 grams and it decomposes at a very high temperature i.e. at 287 degree centigrade.
It is readily soluble in water and also dissolves in alcohol.
Now considering the statement as;
The structure formula of the fumaric acid having the molecular formula as $H{{O}_{2}}CCH=CHC{{O}_{2}}H$ is ;

So, thus, option d is correct.

Note: Don’t get confused in the fumaric acid and the maleic acid. Fumaric acid is the trans isomer of the butenedioic acid whereas on the other hand, maleic acid is the cis isomer of the butenedioic acid. The structural formulas of both fumaric acid and the maleic acid is as;
