Saturated or unsaturated?
Unsaturated
Pi or sigma bonds?
3/4 electrons have sigma bonds
1/4 electrons has a pi bond
What does the pi bond do?
locks the 2 carbon atoms in position and prevents them from rotating around the double bond
Shape around a double bond?
Trigonal planar
3 regions of electron density around each of the carbon atoms
3 regions repel as far apart as possible- bond angle = 120
What is a pi bond?
The sideways overlap of 2 p orbitals
Why is the shape and bonding that way?
Trigonal planar
3 regions of electron density around the carbon atoms
3 regions repel eachother as far apart as possible
120 degrees
