The common name for the ether whose IUPAC name is ethoxyethane has to be chosen from the given options. Concept Introduction: Any organic molecule can be named by using certain rules given by IUPAC (International Union for Pure and applied chemistry). IUPAC name consists of three parts in major namely Prefix suffix and root word. Prefix represents the substituent present in the molecule and its position in the root name. Suffix denotes the presence of functional group if any in the molecule. It can be an alkene , alkyne , alcohol, carboxylic acid , alcohol etc. Root word represents the longest continuous carbon skeleton of the organic molecule. Rules for assigning common names to ether: For obtaining common name for ether, two rules are applicable, one for symmetrical ethers and one for unsymmetrical ethers. ✓ For unsymmetrical ethers, the two hydrocarbon groups that is attached to the oxygen atom is arranged in a alphabetical order and the word ether is added. The words are separated by a space. These names have three words with space between them. ✓ For symmetrical ethers, prefix di- is used. Then the word ether is added with a space between the two words. These names have two words with space between them.

Interpretation Introduction

Interpretation:

The common name for the ether whose IUPAC name is ethoxyethane has to be chosen from the given options.

Concept Introduction:

Any organic molecule can be named by using certain rules given by IUPAC (International Union for Pure and applied chemistry). IUPAC name consists of three parts in major namely Prefix suffix and root word.

Prefix represents the substituent present in the molecule and its position in the root name.

Suffix denotes the presence of functional group if any in the molecule. It can be an alkene, alkyne, alcohol, carboxylic acid, alcohol etc.

Root word represents the longest continuous carbon skeleton of the organic molecule.

Rules for assigning common names to ether:

For obtaining common name for ether, two rules are applicable, one for symmetrical ethers and one for unsymmetrical ethers.

✓ For unsymmetrical ethers, the two hydrocarbon groups that is attached to the oxygen atom is arranged in a alphabetical order and the word ether is added. The words are separated by a space. These names have three words with space between them.

✓ For symmetrical ethers, prefix di- is used. Then the word ether is added with a space between the two words. These names have two words with space between them.
