Alkanols, Ethers And Amines Flashcards
(12 cards)
What is the trend in boiling point of alcohol?
Increases as chain length increases
What is the trend is solubility of alcohols ?
Smaller alcohols dissolve in water as they can form H bonds to water molecules
How does an alcohol act has an acid ?
It reacts with an alkali to form an alkoxide (base) and hydrogen gas
How do alcohols act as a base ?
They form an oxonium ion
Primary oxonium ion is then converted into an alkene
A secondary and tertiary oxonium ion is converted into a carbocation
What are primary alcohols oxidised into ?
Partial oxidation= aldehyde
Full oxidation= Carboxylic acid
E2 reaction
What are secondary alcohols oxidised into ?
Ketones
Why can’t tertiary alcohols be oxidised ?
There are no hydrogens bonded to the carbon with the -OH group
What are ethers ?
They have R-O-R’
An oxygen bonded to 2 carbons by single bonds
Trend in boiling point of ethers
Increases as chain length increases
What are ethers used as ?
Solvents as they have little chemical activity
What is an ammonium ion ?
NH4
What mechanism are amines used in ?
Nucleophilic addition elimination
