Question: Write down an isomer of \({C_2}{H_5}OH\)....

Write down an isomer of C2H5OH{C_2}{H_5}OH.

Explanation

Solution

Isomers are the compounds which have the same molecular formula but have the different structural arrangement of atoms or molecules. One can think about the possible structures the given ethanol can have which must have different structures from the initial one and must have the same number of atoms as in the initial structure. One can think about the different functional groups which can fit in the given molecular formula and give the different structural arrangement.

Complete step by step answer:

  1. Lets first of all discuss the concept of isomer which will give a better approach to solve the given question. The Isomers are the chemical compounds which have the same molecular formula but have the different structural arrangement of atoms or molecules.
  2. While a compound having a different structural formula that means that the compound may have different arrangements of the atoms and molecules present in which the same functional group can be attached to different atoms in the structure.
  3. Also the isomer compounds can have different functional groups in their separate isomeric structure. But the condition here is that both the isomeric structures must have the same number of atoms which can be said as the same molecular weight of both isomeric structures.
  4. Now, after analyzing all the above data let's find out the isomer for C2H5OH{C_2}{H_5}OH which has an alcohol functional group −OH - OH where oxygen is present in the functional group. There is one other functional group that has oxygen in the functional group which is ether and denoted as R−O−RR - O - R
  5. Let's analyze the possible ether structure, which is CH3−O−CH3C{H_3} - O - C{H_3} now in this structure the number of atoms and the molecular formula is the same as that of the structure C2H5OH{C_2}{H_5}OHwhich means this is an isomer of C2H5OH{C_2}{H_5}OH)

Note:
The isomers do not have similar chemical properties or physical properties. Isomerism has the two main types of isomerism which are structural isomerism and stereoisomerism. In structural isomerism the bonds between the atoms differ with each other while in stereoisomers are in which the bonds are the same but the relative positions of the atoms differ in their structure.
