a: pi bonds ~
b: pointing two fingers at the ceiling
What:
"Pi bonds are like pointing two fingers at the ceiling and moving them sideways until they touch. Unlike sigma bonds, pi bonds cannot rotate and maintain the bond; you can see this in our finger model, as turning your fingers out of alignment breaks the connection. Therefore, double or triple-bonded atoms cannot rotate relative to each other."
