Addition reactions of alkenes and alcohols Flashcards
What is the general formula for alkenes?
CnH2n
Name the first four alkenes
- Ethene
- Propene
- Butene
- Pentene
What must ALL alekenes have?
Double covalent bond between adjacent carbon atoms
What is the molecular formula for ethene?
C2H4
What is the molecular formula for propene?
C3H6
What is the molecular formula for butene?
C4H8
What is the molecular formula for pentene?
C5H10
Are alkenes saturated or unsaturated?
Unsaturated
Why are alkenes unsaturated?
They have 2 fewer hydrogen atoms for the same number of carbon atoms
What is it called when alkenes react with hydrogen?
Hydrogenation
What is the functional group in alkenes?
The carbon to carbon double bond
What is meant by a functional group?
The part of a molecule which determines how it reacts
What is produced when alkenes react with hydrogen?
An alkane
A not E, because it becomes saturated
What happens to alekenes when they react with hydrogen?
They become saturated
What conditions are required to react hydrogen with alkenes?
150 degrees Celcius
Nickel Catalyst
