Section 13.2 from Chemical Ideas
This Power Point uses some of the material from Chemical Ideas Salters Advanced Chemistry Section 13.2 It has been designed fro use with Unit WM in part of the A2 course. It can be used as an introduction or set up as a looped animation at the start of a lesson. JB

2. C2H6O There are two Isomers with this molecular formula
Ethanol and methoxymethane

3. Ethanol Belongs to the homologous series called alcohols
All members of the group contain the hydroxyl functional group…………. –OH
They only differ in the length of their hydrocarbon chain

4. Methoxymethane Belongs to the homologous series called ethers
All ethers contain the alkoxy group…… -OR

5. Alcohols They are named from the parent alkane by omitting the final –e and adding -ol
CH3-OH
CH3-CH2-OH
CH3-CH2-CH2-OH
CH3-CH2-CH2-CH2-OH
methanol
ethanol
propan-1-ol
butan-1-ol

6. Ethers
Ethers are derived from alkanes by substituting an alkoxy group ( -OR ) for an H atom, for example
CH3 – CH2 - O- CH2-CH3
ethoxyethane
CH3 – CH2 – CH2- O- CH3
Methoxypropane
Note that the longer hydrocarbon chain is chosen as the parent alkane
