Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain the ether functional group and its chemistry, identify ether-containing compounds, give laboratory safety guidance, and separate the historical anaesthetic and other senses.

A class of organic compounds containing an oxygen atom bonded to two alkyl or aryl groups, from simple diethyl ether and dimethyl ether to cyclic ethers such as tetrahydrofuran, crown ethers, polyethers such as polyethylene glycol and polyoxymethylene, and ether groups within drugs and cellulose derivatives; ethers are common solvents, fuels and structural motifs and require care because of flammability and peroxide formation.

What it is for: Organic chemistry and its applications.

It can be explain ether structure and properties; identify ether-containing compounds; give safety guidance for ether solvents; separate senses.

Distinguishing features

Oxygen between two carbons

Relatively unreactive

Volatile and flammable

Peroxide-forming

What it looks like

Typically volatile, colourless liquids with a characteristic smell; polyethers are solids or viscous liquids.

How it is recognised

R-O-R functional group

Low reactivity, good solvents

Esters have a carbonyl next to the oxygen
