How molecules stick together

    Cards (8)

    • 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
