  • If a molecule has 2 electron pairs what is its shape and bond angle?
    Linear
    180 degrees
  • what is the shape and bond angle of a molecule with 3 electron paris?
    triginal planar
    120 degrees
  • what is the shape and bond angle of a molecule with 4 electron pairs ?
    tetrahedral
    109.5 degrees
  • as the number of lone pairs in a molecule increases the…
    bond angle decreases
  • why do lone pairs repel more than bonding pairs
    lone pairs has a bigger charge cloud than a bonding pair
  • If a molecule has 2 bonding pairs and 1 lone pair what is the shape and bond angle?
    bent
    <120
  • What are the assumptions we make when using VESPR

    Electron pairs repel as far as possible
    lone pairs repel more than bonding pairs
  • What do we assume when predicting the shape of a molecule with a double bond? 

    The electron pairs in a double bond dont repel each other
