Answer Details
The relationship between the two compounds is that they are isomers.
To understand why these compounds are isomers, let's break down their structures and definitions:
1. Structures of the Compounds:
The first compound, CH3-CH2-OH, is known as ethanol. This compound is composed of two carbon atoms (C), six hydrogen atoms (H), and one oxygen atom (O).
The second compound, CH3-O-CH3, is known as dimethyl ether. This compound also consists of two carbon atoms (C), six hydrogen atoms (H), and one oxygen atom (O).
2. Definitions:
Isomers: Compounds that have the same molecular formula (same types and numbers of atoms) but different structural arrangements and properties.
Allotropes: Different physical forms of the same element (e.g., carbon can exist as diamond, graphite, etc.).
Isotopes: Atoms of the same element that have the same number of protons but different numbers of neutrons in their nuclei.
Isobars: Atoms of different elements that have the same atomic weight (mass number) but different atomic numbers.
Both compounds have the same molecular formula: C2H6O. However, they have different arrangements of their atoms. Ethanol has a hydroxyl group (-OH) attached to an ethyl group (CH3-CH2-), while dimethyl ether involves two methyl groups (CH3-) bonded to an oxygen atom (O). This difference in structure leads to different chemical and physical properties, despite having the same molecular formula. Hence, these two compounds are classified as isomers.
