Question

The IUPAC name of ${{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}{\text{O}}{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}$is
A.Diethyl ether
B.Ethoxy ethane
C.Ethoxy propane
D.Dimethyl ether

Answer 1

Hint: Diethyl ether is also known as ether. Ether is a colourless, volatile, flammable liquid with a distinct odour. It is a member of the ether family of organic molecules. Ethyl ether is another name for it. Inhaling diethyl ether can produce headaches, nausea, vomiting, and even loss of consciousness. It irritates the skin and eyes when it comes into touch with them. Diethyl ether exposure at high levels can harm the kidneys.

Complete answer:
Ethers are organic compounds that include an oxygen atom that is linked to two alkyl or aryl groups, which can be the same or different. Ethers have the generic formula R-O-R, where R stands for an alkyl group. The rule for naming ethers is to name distinct alkyl/aryl groups linked to the oxygen atom on either side in alphabetical sequence, then add the word ether to the end.
Because the ether functional group lacks a distinctive IUPAC nomenclature suffix, it must be designated as a substituent. To do so, the most frequent alkoxy substituents are given alkyl component-derived names. The IUPAC nomenclature for ethers follows a set of rules. A substituent group with more carbon atoms is chosen as the parent hydrocarbon according to IUPAC nomenclature. The prefix "oxy" is used to designate the other substituent group linked to the oxygen atom. \[{\text{C}}{{\text{H}}_{\text{3}}}{\text{O}}{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}\] is known as 1-methoxy ethane, for example.
Ethers are called by using a different term for each of the two carbon groups, followed by a space, then the word ether. The group name alkox can also be used to name the -OR group as a substituent. The alkoxy substituent is the smaller, shorter alkyl group. The alkane base term is given to the side of the alkyl group that is bigger and longer. Each alkyl group on each side of the oxygen is given its own number. The carbon nearest to the oxygen has the highest numbering priority. With its matching alkyl group, the alkoxy side (shorter side) bears a "-oxy" ending.
So, in ${{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}{\text{O}}{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}$ the IUPAC name is Ethoxy ethane.

Note:
Inhaling Diethyl Ether might irritate the nose and throat. Drowsiness, arousal, dizziness, vomiting, uneven breathing, and saliva are among symptoms of inhaling Diethyl Ether. High levels of exposure might cause unconsciousness or even death. Ether is still used as an anaesthetic in numerous underdeveloped nations due to its inexpensive cost and high therapeutic index, which reduces cardiac and respiratory discomfort. Because of its flammability, it is no longer used in most developing nations.
