Shapes of molecules

• Name of molecules pt1

  BeCl2

  The name of the shape is called planar

  2 bond pairs

  0 lone pairs

  
• Names of molecules pt2

  BF3

  Shape is called trigonal planar

  120 ° bond angle

  3 bonds pairs

  0 lone pairs

  
• Names of molecules pt3

  CH4

  Shape is called tetrahedral

  4 bond pairs

  0 lone pairs

  109.5 ° bond angle

  
• Shapes of molecules pt4

  PCl5

  Name of the shape is called trigonal bipyramidal

  5 bond pairs

  0 lone pairs

  120 ° and 90 ° bond angles

  
• Shapes of molecules pt5

  SF6

  6 bond pairs

  0 lone pairs

  The shapes name is called octahedral

  90 ° is the bond angle

  
• Shapes of molecules pt6

  2 bond pairs

  1 lone pairs

  Shape of molecule is V shaped

  Bond angle 117.5 ° because it's a trigonal planar shape with a lone pairs instead of bond pairs so you would do 120° - 2.5 °

  
• Shape of molecules pt7

  1 lone pairs

  3 bond pairs

  Name of shape is called trigonal pyramidal

  Bond angle is 107 ° ( 109.5-2.5)

  
• Shapes of molecules pt8

  2 bond pairs

  2 lone pairs

  Shape of molecule is V shaped

  Bond angle is 104.5 °

  
• Shapes of molecules pt9

  4 bond pairs

  1 lone pairs

  89 ° and 119 ° bond angles

  Shape of molecule is called see-saw shape

  
• Shapes of molecules pt10

  3 bond pairs

  2 lone pairs

  Shape of molecule is called Trigonal planar or T shaped

  89 ° bond angles

  
• Shapes of molecules pt11

  5 bond pairs

  1 lone pairs

  Shape is called square pyramidal

  Bond angle is 89 °

  
• Shapes of molecules pt12


  4 bond pairs

  2 lone pairs

  90 ° bond angles

  Shape of molecule is called square planar

  
• VESPR theory

  Since lone pairs repel more that bond pairs, lone pairs create the shape of the molecules
