Are alkenes saturated or unsaturated? Why?
Alkenes are unsaturated because they could hold more hydrogen if the double bond was broken
What are cycloalkanes?
saturated hydrocarbons made up of carbon atoms joined in rings
What does Unsaturated mean?
double bonds
What does it mean if a carbon has 4 bonds?
Saturated
What is cis-trans isomerism?
Two of the groups are the same attached to the C=C
What is a cis isomer?
the two Xs are on the same side
What is a trans isomer?
the two x's are on opposite sides
A tetrahedral molecule has what bond angle?

What kind of bond angle does Ethylene have?
120
A linear molecule has what bond angle?
180
What is a stereo structure?
Same Molec Formula and attachment
Different spatial arrangement
What is a constitutional isomer
differ in the order of attachment of atoms
What is isomerism?
Compounds that have the same molecular formula but different structural formula
When is cis-trans possible?
When an Alkene has two different substituent groups pn each end.
If One of the carbons containing the double bond is attatched to both identical groups, is cis trans possible?
Nope.
