Elimination reactions involving halogenoalkanes

Elimination from 2-bromopropane . . .

The formation of an alkene (propene) from 2-bromopropane.

Elimination from unsymmetrical halogenoalkanes . . .

Explains how to cope with cases where more than one elimination product can be formed from a single halogenoalkane.

Elimination v. substitution . . .

Discusses how the reaction between a halogenoalkane and hydroxide ions can lead to either an elimination reaction or nucleophilic substitution.

 

The dehydration of alcohols

The dehydration of propan-2-ol . . .

Facts and mechanism for the dehydration of propan-2-ol (as typical of secondary and tertiary alcohols) using an acid catalyst to give propene.

The dehydration of ethanol . . .

Facts and mechanism for the dehydration of ethanol (as typical of primary alcohols) using an acid catalyst to give ethene.

You must read the propan-2-ol page before you go to this one.

The dehydration of butan-2-ol . . .

Explains how to cope with cases where more than dehydration product is possible.

You must read the propan-2-ol page before you go to this one.
