These are the IUPAC names;
1. CH3OCH3- Methoxymenthane
. CH3CH2OCH2CH3-Ethoxyethane
. (CH3CH2CH2CH2)2O-Butoxymenthane 
. CH3CH2OCH3-Methoxyethane

2.Properties of ethers are;
. Physical states; at room temperature, ethers are colorless, neutral liquids with pleasant odours. 
. Solubility; ethers are soluble in water than are the the corresponding alcohols. They are miscible with organic solvents. 
. Density; Most of the simple ethers are less dense in water although the density increases with increasing relative molecular mass.
. Boiling point; low molecular mass ethers have a lower boiling point than the corresponding alcohols but those ethers containing alkyl radicals larger than four carbon atoms, the reverse is true.
.Reactivity; Ethers are inert at moderate temperature. thier inertness at moderate temperatures leads to the wide use as reaction media.
3. Two methods of preparing ethers are;
. Controlled catalytic hydration of oilfins
2CH3CH=CH2+H2O   (CH3)CH-O-CH(CH3)2
. From haloalkanes and dry silver(1) oxide
2RX + Ag2O    -warm-----------  R-O-R + 2AgX
4. Three uses of  etheylene oxide are;
. Ethylene oxide is used as an intermidiate in the  manufacture of ethylene glycol
. Ethylene oxide is used in the preparation of nonionic emulsifying agents, plastics,plasticizers and several synthetic textiles.
.Ethylene oxide is used as a gaseous sterilizing agent.
