Covalent Bond Angles and Lengths

Some Single Bond Angles and Lengths

 

 

methane

 

water

 

ammonia

From studying the geometry of the above molecules you should notice

109.5 for methane
105 for water
107 for ammonia

110 A for methane
0.96 A for water
1.01 A for ammonia

In biological terms, the fact that covalent bonds have define bond lengths and angles means that biological molecules have defined and predictable shapes.
