Flashcards in Alkenes Deck (8):
What kind of bond does an alkene have?
A double carbon bond

Why are alkenes unsaturated?
They can make more bonds - the double bond can open up, allowing the 2 carbon atoms to bond with other atoms
What is the general formula for alkenes?
What are the first 2 alkenes?
Ethene (2 carbons) and Propene (3 carbons)
What is the formula and structure of ethene?
> C == C <
What is the formula and structure of Propene?
H H H
H--C -- C == C <
How do you test for an alkene?
1) Adding the substance to bromine water
2) An alkene will decolourise the bromine water, turning it from orange to colourless
